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 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.
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)
,
pipe sizing or
other restrictions in the system.
WARNING
Failure to comply with all applicable local, state, and federal gas codes could result in serious personal
injury and/or serious property damage.
