INSTALLATION
GENERAL
Code Requirements
Installation must be in accordance with local codes,
or in the absence of local codes, with the latest
edition of the National Fuel Gas Code, ANSI Z223.1,
(a portion of the 1996 code relating to ventilation is
excerpted in Figure 3) the National Electrical Code,
ANSI/NFPA 70. Canadian installations should
conform with CSA-B149.1, Natural Gas and
Propane Installation Code, and CSA-C22.1,
Electrical code, and/or local installation codes. {Les
installations canadiennes doivent se conformer aux
CODES D’INSTALLATION CSA-B149.1, Natural
Gas and Propane Installation Code, et CSA-C22.1,
Electrical Code, et/ou aux codes locaux
d’installation.}
1. Place the unit (with the 4" [102 mm] diameter flue
adapter facing toward the rear) directly on top of
the Hatco PMG-60 Gas Booster Heater, nesting
the assembly with the brackets inside of the
Auxiliary Hood.
2. Connect 4" (102 mm) diameter flue pipe to the
adapter to direct the flue gas up to 20 linear feet
(6 meters) away from the unit.
NOTE: Each elbow equals 5 linear feet (1.5 m).
3. Terminate the flue pipe at a location that will not
become obstructed, so that it will not exhaust
directly toward any combustibles.
EXCERPT FROM ANSIZ223.1/NFPA #54
7.2.1 Connection To Venting Systems. Excerpt as
permitted in 7.2.2 through 7.2.6, all gas utilization
equipment shall be connected to venting systems.
7.2.2 Equipment Not Required To Be Vented.
A single booster-type [automatic instantaneous] water
heater, when designed and used solely for the
sanitizing rinse requirements of a dishwashing
machine, provided that the equipment is installed, with
the draft hood in place and unaltered, if a draft hood is
required in a commercial kitchen having a mechanical
exhaust system. Where installed in this manner, the
draft hood shall not be less than 36 inches (914 mm)
vertically and 6 inches (152 mm) horizontally from any
surface other than the equipment.
Where any or all of this equipment is installed so the
aggregate input rating exceeds 20 Btu per hour per
cubic foot (207 watts per m
3
) of room space in which it
is installed, one or more shall be provided with venting
systems or other approved means for removing the
vent gases to the outside atmosphere so the aggregate
input rating of the remaining unvented equipment does
not exceed the 20 Btu per hour per cubic foot (207
watts per m
3
) figure. Where the room or space in which
the equipment is installed is directly connected to
another room or space by a doorway, archway or other
opening of comparable size that cannot be closed, the
volume of adjacent room or space shall be permitted to
be included in the calculation.
WARNING
The flow of air to the heater for combustion and
ventilation must not be obstructed. Air vents on
the bottom and side of the unit should never
be blocked.
WARNING
Flue gases exit top sides of this unit and must
not be obstructed, specified clearances must
be maintained for safe operation.
WARNING
DO NOT VENT THIS UNIT OUTDOORS. This
unit is designed to vent directly into the room
and is intended for commercial food service
water heating only. IT IS NOT FOR
RESIDENTIAL USE.

WARNING
If an external electrical source is utilized, the
appliance, when installed, must be electrically
grounded in accordance with local codes, or,
in the absence of local codes, with the National
Electrical Code, ANSI/NFPA 70, CSA C22.1,
Electrical Code.
