Check the rating plate to verify that the heater is appropriate for the installation site.

VCS-VCT-VPS-VPT-IOM (08-23) 1042552-C

Installation Codes

•These units must be installed in accordance with local building codes. In the absence of local codes, in the United

States, the unit must be installed in accordance with the National Fuel Gas Code, ANSI Z223.1 /NFPA 54. A

Canadian installation must be in accordance with the CSA B149 Natural Gas and Propane Installation Code. This

code is available from CSA Information Services, 1-800-463-6727. Local authorities having jurisdiction should be

consulted before installation is made to verify local codes and installation procedure requirements.

•Installations in aircraft hangars should be in accordance with ANSI/NFPA No. 409 (latest edition), Standard for

Aircraft Hangars. Installations in public garages should be in accordance with ANSI/NFPA No. 88A (latest edition),

Standard for Parking Structures. Installations in repair garages should be in accordance with ANSI/NFPA No. 88B

(latest edition), Standard for Repair Garages. In Canada, installations in aircraft hangars should be in accordance

with the requirements of the enforcing authorities, and in public garages, in accordance with the CSA B149 code.

•If the heater is being installed in the Commonwealth of Massachusetts, installation must be performed by a licensed

plumber or licensed gas fitter.

Heater Location

⚠ CAUTION ⚠

• Heaters should not be used in an application where the heated space temperature is below 40°F

(4°C). Operating under low ambient conditions may cause condensation to form in the heat

exchanger.

• Do not locate the heater where it may be exposed to water spray, rain, or dripping water.

Mounting Height Requirements

⚠ WARNING ⚠

If touched, the vent pipe and internal heater surfaces that are accessible from outside the heater

will cause burns. Suspend the heater a minimum of 12 feet (3.7 meters) above the floor.

NOTE: Suspended heaters are most effective when located as close to the working zone as

possible, and this fact should be kept in mind when determining the mounting heights to be used.

Hazards of Chlorine

NOTE: Remember, chlorine is heavier than air. This fact should be kept in mind when determining

the installation location of heaters and building exhaust systems.

The presence of chlorine vapors in the combustion air of heating equipment presents a potential corrosion hazard.

Chlorine, found usually in the form of Freon or degreaser vapors, when exposed to flame will precipitate from the

compound and form a solution with any condensation present in the heat exchanger or associated parts. The result

is hydrochloric acid, which readily attacks all metals, including 300 grade stainless steel. Care should be taken to

separate these vapors from the combustion process. This may be done by wise location of the unit with regard to

exhausters or prevailing wind directions.

Clearances

⚠ DANGER ⚠

• All listed minimum clearances to combustible materials MUST be adhered to at all times. Adequate

clearance MUST be provided around air openings into the combustion chamber, and there MUST

be suitable clearance for accessibility and for combustion/ventilation air.

• Minimum clearance from the heater must be maintained from vehicles parked below heater. In all

situations, clearances to combustibles must be maintained. Signs should be posted in storage

areas to specify maximum stacking height to maintain required clearance to combustibles.

Such signs must either be posted adjacent to the heater thermostats or—in the absence of such

thermostats—in a conspicuous location.

⚠ CAUTION ⚠

Building materials with low heat tolerance (plastics, vinyl siding, canvas, tri-ply, etc.) may be subject

to degradation at lower temperatures. It is the installer’s responsibility to ensure that adjacent

materials are protected from degradation.

Clearance to combustibles is defined as the minimum distance from the heater to a surface or object for which it is

necessary to ensure that a surface temperature of 90°F (50°C) above the surrounding ambient temperature is not

exceeded. Units must be installed so that clearances are in accordance with Table 5.

Heater Assembly

⚠ WARNING ⚠

Safety boots and protective gloves and eyewear are recommended.

Systems are shipped disassembled and are comprised of a burner cabinet and tube assemblies. Refer to the SYSTEM

CONFIGURATIONS section for assembly details of specific systems.

NOTE: For aesthetic reasons, it is advisable to position all emitter tube seams facing down and

to install coupling fasteners so that they cannot be seen from beneath the heater.

1. Position emitter tubes on saw horses and mark position of bracket centers.

2. Install turbulator strip(s):

a. Interlock turbulator strip sections as shown in Figure 10, DETAIL A and slide connected sections into emitter

tube(s). Add further strips to form required length.

b. Where heater configuration requires more than three turbulator strips and exhaust heat exchanger tube is

adjacent to L- or U-tube, install turbulator strips as shown in Figure 10, DETAIL B.

c. Install turbulator strip into open end of last emitter tube only after it has been suspended and connected to

previous emitter tube.

4. Install couplers to join emitter tubes and L- or U-tubes (see Figure 12):

a. Slide coupler over tube joint.

b. Moving between coupler pins or bolts, apply equal pressure to tighten each in turn. DO NOT OVERTIGHTEN.

c. Complete assembly by installing self-tapping retention zip screws.

Figure 12. Typical Coupler

5. Install brackets:

a. Slide suspension brackets (see Figure 13, DETAIL A) onto emitter tube assembly and position them in

accordance with SYSTEM CONFIGURATIONS section.

b. Install tube strap (see Figure 13, DETAIL B) on suspension bracket that will be closest to burner cabinet:

(1) Loosen tube strap nut and bolt.

(2) Position strap over emitter tube and hook both strap ends onto suspension bracket.

(3) Tighten nut and bolt.

c. Install reflector brackets (see Figure 13, DETAIL C):

(1) Remove bracket nut and bolt.

(2) Position bracket over emitter tube and re-install nut and bolt hand-tightened—nut and bolt will be tightened

after reflectors are installed as bracket positioning may need to be adjusted.

Figure 13. Bracket Installation

6. Install reflectors in accordance with SYSTEM CONFIGURATIONS section:

a. Remove protective plastic from reflector(s) and slide reflectors through suspension brackets until they overlap

each other.

b. Secure reflectors by tightening screws (non-slip overlap) on reflector brackets installed in step 5c as shown

in Figure 14, DETAIL A.

DETAIL A DETAIL B DETAIL C

Figure 14. Non-Slip and Slip Reflector Bracket Overlaps

c. For every other reflector bracket, create slip overlap by not tightening reflector bracket screws (see Figure 14,

DETAIL B) to allow reflector to float for adjustment.

d. Alternate slip with non-slip overlaps over entire length of tube assembly as shown in Figure 15.

e. Install corner reflectors over L- and U-tube sections.

Figure 15. Typical Bracket Configuration

7. Raise tube assembly into position and suspend from previously fixed chains in accordance with Heater Suspension

section. Longer tube assemblies may be raised in more than one subassembly—final emitter tube connection

may be made while tube assembly is suspended.

8. For unit size 200 units with S50 tube configuration, replace fan orifice plate with plate provided with each unit.

Access fan as necessary in accordance with Fan and Motor Assembly Maintenance section.

9. Raise burner cabinet into position, suspend in accordance with Heater Suspension section, and connect to tube

assembly.

10. For system configurations that require them, install end caps:

a. Position end cap beneath reflector with end cap flanges facing inward and secure using four Z-clips (see

Figure 16).

Heater Suspension

⚠ DANGER ⚠

• When installed, tubular radiant heaters must be able to expand, must be level, and must be

restricted from too much lateral sway.

• The heater must be level for proper operation. DO NOT place or add additional weight to a

suspended heater.

• Before suspending the heater, check the supporting structure to be used to verify that it has

sufficient load-carrying capacity to support the weight (refer to Weights section) of the unit.

• Heaters should be suspended at a height that has been determined to be most efficient for the

application (refer to Mounting Height Requirements section). Clearances to combustibles must

be observed (refer to Clearances section).

⚠ CAUTION ⚠

• To allow for expansion, the chain length between the suspension point and the heater, including

S-hook(s) and turnbuckle(s) (if used), must be a minimum of 12 inches.

• One chain link consists of two loops. When cutting chain, ensure that the entire two-loop link

is removed.

NOTES:

• In the event that suitable roof steelwork is unavailable, install additional steelwork to enable

vertical hangers to be installed for suspending the heater.

• The use of turnbuckles for heater suspension is recommended for convenience in leveling the

system. Use either a Reznor turnbuckle kit or field-supplied steel, stainless steel, or malleable

iron turnbuckles.

• Each straight tube must have at least one suspension point. The heaters are designed so that

the tube suspension points can be adjusted slightly to adapt to the structure. Straight tubes

downstream and adjacent to an L-tube or U-tube require two suspension points. The installer

is responsible for installing the structure suspension points and for adequately supporting the

weight of the heater. Suspension point hardware is field-supplied.
