NOTE: THE REGULATOR HAS BEEN FACTORY PRE-SET. IF THE PRESSURE IS
INCORRECT, CHECK THE SUPPLY PRESSURE FIRST, BEFORE MAKING ANY
ADJUSTMENTS TO THE APPLIANCE. ALSO, IF THE LOW CONTROL PRESSURE
CANNOT BE OBTAINED IN STEP 12, ADJUST THE ADJUSTMENT SCREW ON THE
PROPORTIONAL VALVE TO ROUGHLY SET PRESSURE AND THEN RECHECK
BOTH THE LOW AND HIGH FIRE PRESSURES. SEE STEP 12 FOR LOW FIRE
PRESSURE AND STEP 15 FOR HIGH FIRE PRESSURE.
1. The conversion shall be carried out by a manufacturer’s authorized representative in accordance with the
requirements of the manufacturer, provincial or territorial authorities having jurisdiction and in accordance with the
requirements of the CAN/CGA-B149.1 or CAN/CGA-B149.2 Installation Codes.
2. Verify proper input rate by:
Confirm differential pressure for which gas unit is converted to:
NAT.(High/Low) 3.7/2.0”W.C.
LPG(High/Low) 10.1/4.3”W.C.
Confirm proper orifice size:
NAT.(High/Low) 0.071/0.077 inches
LPG(High/Low) 0.037/0.047 inches
3. Manifold pressure for high altitude 2000 4500ft(610 1370m)
NAT.(High/Low) 2.7/2.0”W.C.
LPG(High/Low)
7.3/4.3”W.C.
13. Press the Economy button to enter the high fire pressure
into memory.
The LED display will indicate “78”.
14. Press the ON/OFF button again.
The LED display turns blank and the unit returns to the
normal OFF mode.
15. Reconfirm all pressure settings before putting said unit
back into operation. Next, disconnect your manometer
from the unit and reinstall the 1/8” test port plug. Leaks test
all connections once the conversion process has been
completed.
16. After completion of gas pipe connections, all joints
including the heater must be checked for gas tightness by
means of leak detector solution, soap and water, or an
equivalent nonflammable solution, as applicable.
CAUTION: Since some leak test solutions, including soap
and water, may cause corrosion or stress cracking, the
piping shall be rinsed with water after testing, unless it has
been determined that the leak test solution is non-
corrosive.
17. Visual check for proper main burner flame appearance.
18. Make sure all markings provided in the kit are in the
appropriate location on the converted appliance.
