NOTE: If using the inlet pressure tap on the White-
Rodgers 36J54 gas valve, then use the 36G/J Valve
Pressure Check Kit, Part No. 0151K00000S.
3. Turn ON the gas supply and operate the furnace and
all other gas consuming appliances on the same gas
supply line.
4. Measure furnace gas supply pressure with burners
firing. Supply pressure must be within the range
specified in the Inlet Gas Supply Pressure table.
If supply pressure differs from table, make the necessary
adjustments to pressure regulator, gas piping size, etc.,
and/or consult with local gas utility.
5. Turn OFF gas to furnace at the manual shutoff valve
and disconnect manometer. Reinstall plug before
turning on gas to furnace.
6. Turn OFF any unnecessary gas appliances stated in
step three.
Gas Manifold Pressure Measurement and
Adjustment
To prevent unreliable operation or equipment damage, the
gas manifold pressure must be as specified on the unit rating
plate. Only minor adjustments should be made by adjusting
the gas valve pressure regulator.
Only small variations in gas pressure should be made by
adjusting the gas valve pressure regulator. The manifold
pressure must be measured with the burners operating. To
measure and adjust the manifold pressure, use the following
procedure.
1. Turn OFF gas to furnace at the manual gas shutoff
valve external to the furnace.
2. Turn off all electrical power to the system.
3. Outlet pressure tap connections:
White-Rodgers 36J54 valve: Back outlet pressure
test screw (inlet/outlet pressure tap) out one turn
(counterclockwise, not more than one turn).
4. Attach a hose and manometer to outlet pressure tap .
5. Turn ON the gas supply.
NOTE: Follow this procedure to test the gas valve
pressure at 100% firing rate.
CAUTION
Run High Fire
NOTE: the Cool Cloud phone application be used
to assist with all functional tests. See the quick
start guide section for details.
The furnace should be inspected by a qualified installer, or
service agency at least once per year. This check should be
performed at the beginning of the heating season. This will
ensure that all furnace components are in proper working
order and that the heating system functions appropriately.
Pay particular attention to the following items. Repair or
service as necessary.
