Installation & Operation Manual
Upon completion of any testing on the gas
system, leak test all gas connections with a
soap and water solution while main burners
are operating. Do not spray soap and water
solution on the gas valve housing. The use of
an excessive amount of soap and water
solution can damage the valve. Immediately
repair any leak found in the gas train or
related components. Do not operate an
appliance with a leak in the gas train, valves,
or related piping.
NOTICE
Check burner performance by cycling the system while you
observe burner response. Burners should ignite promptly.
Flame pattern should be stable, see the Maintenance Normal
Flame Pattern section in the EnergyRite Service Manual. Turn
system off and allow burners to cool, then cycle burners again to
ensure proper ignition and flame characteristics.
NOTICE
If a pressure drop of more than 2" w.c.
occurs between Stand by (Static) Mode and
Operating (Dynamic) Mode occurs, a gas
volume problem exists. Contact the gas
utility, gas supplier, qualified installer, or
service agency to determine the necessary
steps to provide the proper gas volume to
the appliance.
4. Turn on gas supply at the manual gas cock, turn on LP
gas at tank if required.
5. Turn the power switch to the “ON” position.
6. Ensure that the “ON/OFF” knob or the valve is in the
“ON” position.
7. Set the electronic temperature control to call for heat.
8. Observe the gas supply pressure as all burners are
firing. Ensure that inlet pressure is within the specified
range. Minimum and maximum gas supply pressures
are specified in the Gas Supply section and on the rating
plate.
9. If gas pressure is out of range, contact a gas utility, gas
supplier, qualified installer, or service agency to
determine necessary steps to provide proper gas
pressure to the control.
10. If the gas supply pressure is within normal range,
proceed to remove gas manometer and replace pressure
tap fittings in the gas control.
11. Turn the power switch to the “OFF” position.
12. Shut off gas supply at the manual gas cock in the gas
piping to the appliance. If fuel supply is LP gas, shut off
gas supply at the tank.
13. Remove the manometer and related fittings from the
“inlet” side of the gas valve, replace the 1/8" hex plug in
the tee (Models ER252 - ER402) or gas valve (Models
ER152 - ER202) and tighten.
14. Turn on the gas supply at the manual valve, turn on the
LP gas at the tank if required.
15. Turn the power switch to the “ON” position.
16. Ensure that the “ON/OFF” knob or the valve is in the
“ON” position.
17. Set the electronic temperature control to call for heat.
If proper ignition and burner operation is not achieved after
checking gas supply pressure and setting the correct manifold
pressure, see the Maintenance section in the EnergyRite Service
Manual for Combustion Air Shutter Adjustment. Follow the
procedure to adjust the combustion air fan.
