WARNING
A qualifi ed installer, service agency
or the gas supplier must perform
installation and service on the fuel
delivery system.
Do not use matches, candles, fl ame or
other sources of ignition to check for
gas leaks.
What to do if you smell gas:
Do not try to light the appliance.
Do not touch any electrical switch.
Do not use any phone in the building.
Leave building and contact gas
supplier from neighbor’s phone. If you
cannot reach gas supplier, phone the
fi re department.
When making gas piping joints,
maintain proper ventilation to reduce
breathing hazards.
An exhaust fan may draw products
of combustion into the work
environment creating a possible
hazard to personnel.
Assure all electrical connections are
powered down prior to attempting
replacement or service of electrical
components or connections of the
equipment.

CAUTION
It is essential that only fresh air be
allowed to enter the combustion air
system. Foreign substances, such
as combustible volatiles and lint in
the combustion system can create
hazardous conditions. If foreign
substances can enter the air stream,
the combustion air inlet must be piped
to an outside location. Failure to do so
will void the warranty.
To avoid failures due to poor
combustion, ensure make-up air
system is properly designed.
5. If positive forced ventilation is adopted, ensure that there will be no
appreciable pressure variation in the equipment room.
6. Avoid ventilation which creates a negative pressure in the building as it
will seriously aff ect combustion and proper operation of the stack. Please
note that exhaust fans or similar equipment can create a down draft in the
chimney or starve the burner’s air supply. Either case may result in poor
combustion or nuisance failures. A properly designed make-up air system
in the equipment room will preclude these possibilities and is required to
maintain proper combustion.
NOTE:  A properly designed make-up air system in the equipment room will
preclude these possibilities and is required to maintain proper combustion.
7. Eliminate potential for high risk situations for particulate matter to
be in the combustion air supply (e.g., as a result of construction and
maintenance activities).
Utilities
 The Gas Supply
Adhere to the following for gas supply installation:
1. Install gas piping in accordance with all applicable codes.
2. Ensure pipe and fi ttings used are new and free of dirt or other deposits.
3. Ensure piping is of the proper size for adequate gas supply to the gas head
assembly. Consult your gas company for specifi c recommendations.
4. When making gas piping joints, use a sealing compound resistant to the
action of liquefi ed petroleum gases. Do not use Tefl on tape on gas line
heads.
5. Ensure no piping stresses are transmitted to the equipment. The
equipment shall not be used as a pipe anchor.
6. Ensure all vent connections on diaphragms, gas valves, pressure regulators,
and pressure switches (gas-fi red units) are vented per local code.
7. On gas-fi red units with NFPA valve trains, ensure the vent valve is piped to
atmosphere per local code.
8. During any pressure testing of the system at pressures in excess of 1/2 psig
(14 inch W.C.)., disconnect the heater at the heater manual shutoff valve
(located at the end of the supplied gas train) from the gas supply piping
system.
9. Ensure the supply pressure is regulated by a non-stacking, tight, shut-off
regulator.
10. Arrange gas piping so that it does not interfere with any cover or burner,
inhibit service or maintenance, or prevent access between unit and walls
