CHECK ALL GAS PIPING AND CONNECTIONS FOR LEAKS BEFORE OPPERATING HEATER
It is recommended that the regulator be sized to 30% of the load being supplied.
Gas layout and pipe sizing guidelines are available through your distributor.
GAS PRESSURE should be CHECKED AND ADJUSTED to recommended settings.
Pressure exceeding 10¼" WC (LP) or 5¾"WC (Nat) could void warranty.
CAUTION:
Purge gas supply line of any contaminants, and clean any oils and/or contaminants from
the inside of the hose before attaching the swivel end of certified and approved BLACK high pressure gas hose
assembly (supplied with unit) to valve. Tighten using ¾" and 11/16" wrenches.
Turn on gas supply to the unit and CHECK ALL FITTINGS AND CONNECTIONS FOR LEAKS with soapy water
solution or leak test solution. Rinse with water after testing unless the leak test solution is noncorrosive. Do Not
Use an open flame to check for gas leaks.
To check gas pressure:
FIRST – Go to the furthest heater from the regulator and connect the pressure gauge to the Pressure Tap on the
side of the control. (See below) Turn "ON" only the heater you are testing or if you have a zone system, turn
"ON" all the heaters in the zone. Set the pressure at a Maximum of 10¼" WC (LP gas) or 5¾" WC (NAT gas).
SECOND – Turn "ON" all stoves in the house on the same regulator and check the pressure again. The pressure
should not drop below 9½" WC (LP gas) or 5¼" WC (NAT gas). If the pressure falls below that shown, the
distribution system is inadequately designed. The problem may be a regulator (size or quantity)
other restrictions in the system.
