VENTING AND COMBUSTION PIPING

The venting system is an integral part of the appliance and is designed for proper operation under all
weather conditions and for winds up to 32 miles per hour. The venting system must not be modified or
added on to. The vent outlet must not be altered or extended.
The unit contains an exhaust blower which draws the combustion products out of the heat exchanger
together with dilution air and forces the mixture from the unit to the outside. No special provisions are
required for supplying air for combustion, nor is a chimney required.

4.10 GAS SUPPLY AND PIPING

In Canada, the gas piping should be installed in accordance with CAN/CSA-B149.1 and B149.2,
and in accordance with any local codes. In the United States, the gas piping should be installed in
accordance with (NFGC) NFPA 54 / ANSI Z223.1 and any local codes.
If local codes allow the use of a flexible gas appliance connector, always use a new listed connector.
Do not use a connector which has previously serviced another gas appliance. For a lever-type valve
use only a shut-off gas valve approved by CAN/CSA B149.

4.11 GAS CONNECTIONS

ALWAYS USE A BACKSTOP WRENCH TO PREVENT TWISTING OF THE GAS VALVE.
ANY STRAINS ON THE GAS VALVE CAN AFFECT POSITIONING OF THE ORIFICES
RELATIVE TO THE BURNERS. THIS COULD RESULT IN FAULTY BURNER OPERATION.
ENSURE THAT THE GAS VALVE IS NOT SUBJECTED TO HIGH PRESSURES.
DISCONNECT THE MANUAL SHUT-OFF VALVE AND GAS VALVE DURING ANY
PRESSURE TESTING THAT EXCEEDS 1/2 P.S.I.G. (3.45
