2.2. COMBI INSTALLATION RULES
2.2.1. General Rules for Installation Places of Combi Boilers
No restrcton s avalable for places where Hermetc (C type) comb s
nstalled (devces may be nstalled regardless of the room volume and
ventlaton type). Also, they may be nstalled n partally protected areas
such as balcones, terraces provded that precautons are taken to ensure
boler s frost proof. Comb should be soundly nstalled aganst a buldng
wall. A flexble connecton pece should be used between the comb
and gas lne. Flex lengths to be used n A, B and C type devces should
not exceed dmensons allowed by local gas authortes. Flue outputs
of hermetc comb bolers must be connected to ventlated places wth
ar crculaton. Installaton (postons of ppe output openng based on
varous forms, vertcal, horzontal mnmum dstances, cross secton areas
of channels f gven to channels, etc.) must be carred out accordng to
regulaton standards, current legslaton and n complance wth local
techncal regulatons and the requred techncal procedures.
2.2.2. Places Not Suitable for Installing Hermetical Combi Boilers
• Starways of Buldngs,

• Places drectly subjected to wnd resstance,
• It s forbdden to nstall Hermetc comb (C type) n openngs provdng
clean ar to other unts.
2.2.3. Wall Installation of Combi and Selecting the Installation Place
• Wall nstallaton for the comb boler should be well secured.
• The hanger plate gven as standard wth the comb should be nstalled
accordng to the technque to a full or sem-full brck wall accordng to
nstallaton scheme and wth connecton screws and not to be used for
other purposes.
• If derent materals are used for nstallaton, the comb shall be rendered
out of the warranty scope.
• If the wall of nstallaton s not a brck wall, addtonal support wll be
requred..
• Comb should be nstalled on a wall resstant to fre.
• 1,8 - 2,2 m heght s recommended for nstallaton of the comb hanger

mnmum of 30 cm heght from ground and by leavng at least 5 cm
dstance from both sdes n order to allow easy access for the servce
techncan.
• Comb nstallaton must not performed n envronments contanng
explosve, flammable substances and acd fumes.
• Installaton cannot be made near or ovens, radators or heater devces.
• Hermetc comb bolers can be nstalled n cabnets but at least 5 cm
should be left at both sdes.
• If nstallng n a ftted ktchen at least 30 cm dstance should be left under
the comb and 5 cm each sde for access.
• Do not put electronc devces, corrosve tools, components furnture

2.2.5. Natural Gas and LPG Connection
(Device Category I2H, II2H3P)
Our comb devces are manufactured to be operated wth methane gas
(G20) and L.P.G. Gas supply ppes should be equal to or hgher than 3/4"G
comb connectons. Pror to makng the gas connecton, a thorough nternal
cleanng should be made to all fuel supply nstallaton ppe furnshngs as
possble wastes may dstort smooth operaton and relablty of the comb.
Only a mans gas supply can be used wth the comb (see the label located
on the comb devce). In case of any conversons to the supply, changes
should only be made to the comb by an authorzed professonal. Also, n
case of reduced pressure, the network dynamc pressure (methane or LPG)
used for supplyng the comb should be carefully controlled and wll mpact
the comb boler strength. Ensure that gas valve connecton s correct.
Flammable gas supply ppe should be able to supply correct adequate
gas amount to the boler when the comb s at full power and be projected
and szed accordng to force and local gas company specfcaton and
nstructons n order to guarantee the devce ecency. Connecton system
should comply wth gas company legal regulatons.
2.2.6. Flammable Gas Quality
The comb s desgned to be used wth pure fuel not contanng any foregn
substances; therefore, requred flter systems must be avalable n the gas
supply lne (for ensurng purfcaton of the fuel).
2.2.7. In Case of Using LPG Tank
LPG use s recommended for heat requrements over 24 kW. New LPG stock
tanks may contan settled gas resdues (ntrogen) however, that fouls the
mxture assgned to that devce and may cause abnormal operatons.
- Varous alloy layers may be formed durng transt of LPG gas n tanks
dependng on mxture compostons. That causes a change n heatng
power of mxture assgned to the devce and may compromse ecency of
the devce.
2.2.8. In Case of Using Bottled Gas
• 300 mmSS pressurzed hood should be used for LPG.
• 500 mmSS hood should not be used.
• 370 mmSS pressurzed hood should be used for Propane.
• Do not place tubes n cold places at rsk of snow or.
• Do not place tubes n hot places contanng ovens or
• Do not make connectons wth sngle tubes and use LPG collector set for
double, trple uses.
• The dstance between the collector and tube should be maxmum 125 cm.
• Copper ppe nstallaton should not use for dstances
longer than 125 cm.
• Hose connecton ends should be tghtened wth clamp
and no other tools should be used.
• Gas nstallaton rules wth use of LPG tank and ndustral tubes should
comply wth local standards and to be performed by expert nstallaton
teams and certfed by the company undertakng the constructon. In
case of falng to fulfl these condtons, comb wll not be covered under
warrantee by Warmhaus Authorzed Servces.

2.2.9. Radiator and Domestic Hot Water Installations
Radator and ground heatng nstallaton should be constructed n
accordance wth techncal specfcatons and heat loss calculaton. Radator
type and amount and ground heatng nstallaton ppe amount should
comply wth the heat loss calculaton.
• Radator nstallaton should be desgned as resstng to at least 6 bars.
• If the cty grd pressure s hgher than 6,5 bars, pressure reducer must be
nstalled.
• It s recommended to construct the radator nstallaton as double lne
and wthout usng elbow and jonts as much as possble.
• Straner flter must be nstalled n radator return and tap water (cty grd)
nput lne.
• For example; as the radator cycle's 8 ltres expanson (24 kW) tank can
support maxmum (80 °C'n radator system) 140 ltre and (55. °C n
ground heatng system) 170 ltre nstallaton water expanson, addtonal
expanson tank should be used for larger nstallaton volumes. 170 ltre
nstallaton water expanson, addtonal expanson tank should be used
for larger nstallaton volumes.
• If the room thermostat and thermostatc radator valve wll be used
together; thermostatc valve should not be nstalled n radators n the
place where room thermostat s avalable.
• Cross connecton must be made for ecent functonng n radators
longer than 1,5 m.
• Covers should be used for radator and domestc hot water wall passages
and fxed wth wall clamps to prevent expansons due to heatng.
• Comb can functon under mnmum 0,5 bar domestc hot water pressure
and that corresponds to a very low flow rate and therefore, t shall not
possble to adjust the requested domestc hot water temperature. For
ths reason, domestc hot water lne should be nstalled at shortest
dstance wth ppe havng at least ½” nternal dameter and by usng
elbows as low as possble. At least 1 bar pressurzed grd nput water
should be suppled to ensure adequate domestc hot water. Hydrophore
should be used f requred.

2.2.15. Installation at Partially Protected Exteriors
Installaton Instructons: Ths comb can be nstalled n partally protected
exterors but not ftted n places at rsk of atmospherc damage – and
protected aganst poor weather.(ran, snow, etc.).
Frost protection: Comb devce s equpped wth a system that prevents
frost by automatcally actvatng the pump and boler when the nternal
water s lower than 5°C.
Frost protecton functon only depends on below gven condtons:
- If the comb s correctly connected to gas and electrcal sources;
- If the comb s suppled from gas and electrcty sources n a fxed way;
- If the Comb s not n falure stuaton due to lack of gnton;
- If radator nstallaton pressure s full and radator valves are open;
- Provded man components are not damaged, the comb s protected
aganst frost up to -5°C envronment temperature.
Lowest Temperature -5°C. In case the comb s nstalled n an envronment
wth a temperature lower than -5°C, and gas supply s nterrupted or
passed nto falure due to falng to make gnton, Frost Preventon System
shall not be actvated and frost/falure shall occur n the devce. Followng
nstructons should be followed for preventng the rsk of frost:
- Heatng crcut; ant freeze may be used wth cauton accordng to
manufacturer's nstructons.
In case of havng flammable walls or passages n envronments wth
Hermetc Flue Type, fre resstant nsulaton materal s placed between the
wall and exhaust gas relef ppe.
Materals used for manufacturng the comb are resstant aganst
glycol and propylene based ant-frost lquds. Follow warnngs by
suppler company nstructons for safe dsposal..
- If the comb s correctly connected to the electrcal source;
- If the man swtch s on;
Under these condtons, the comb s protected aganst frost up to -5°C
temperature.
Frost protection of the combi boiler is guaranteed only under these
conditions:
Damages arsng from nterrupton of electrcal power and not followng

3.2.12. Outside Temperature Sensor Use (Optional)
Outsde Temperature Sensor (optonal) can be nstalled n your comb by
our Authorzed Servce (see: Installaton Secton; Accessory Connecton
Scheme), and you can enable automatc temperature adjustment for
the radator wth mmedate responses to outsde weather temperature
changes va smart and comfort operaton
(Fgure 32). Therefore, t mantans an ecent and economc operaton
by reducng the radator water temperature when outsde weather
temperature ncreases and gradually ncreasng the radator water
temperature when outsde weather temperature decreases and sets
you free from makng radator temperature adjustments. Ths sensor s
actvated when connected ndependently from the typology or avalablty
of used thermostat, the relaton between output temperature and outsde
temperature s defned accordng to curves gven n the graphc below
based on poston of button located on the comb panel.
After connectng the Outsde Temperature Sensor, (Fgure 32) adjustment s
made accordng to average external weather temperature of your provnce
wth P04 parameter. Our authorzed servce wll make ths adjustment
durng nstallaton (Fgure 33).
