Bottom Gas Pipe Entry
When bottom entry of gas pipe is used, the side entry hole must
first be completely covered by a field-supplied plug. Route the
pipe up through the bottom entry hole and immediately into an
elbow to route pipe along the base of the unit. Use another elbow
to route gas pipe up through holes provided in control drawer
mount. One more elbow will route the pipe to the union and gas
control valve.

WARNING
FIRE OR EXPLOSION HAZARD
Failure to follow the safety warnings exactly could result
in serious injury, death or property damage.
Never test for gas leaks with an open flame. Use a
commercially available soap solution made specifically
for the detection of leaks to check all connections. A fire
or explosion may result causing property damage,
personal injury or loss of life.

which automatically lights the burner. This furnace cannot be
lighted manually. Do not try to light the burner by hand.

7. Check minimum inlet gas supply pressure.
Turn on all other gas appliances.
Observe the pressure rating on the pressure gauge.
The minimum inlet gas supply pressure is 5 in. W.C. for
natural gas and 11 in. W.C. for propane gas.
8. Check maximum inlet gas supply pressure.
Turn off all other gas appliances.
Observe the pressure reading on the pressure gauge.
The maximum inlet gas supply pressure is 10.5 in. W.C. for
natural gas and 13 in. W.C. for propane gas.
IMPORTANT: If the inlet gas supply pressure is not within the
minimum and maximum range as shown on the rating plate,
contact your gas supplier.
9. Turn off the electrical power to the furnace.
10. Turn off the gas supply at the manual gas shutoff valve.
Remove the pressure gauge tube and the ¹⁄₈ in. hose
connector.
11. Replace the inlet pressure tap plug on the gas control valve.
12. Turn on the gas supply at the manual gas shutoff valve.
13. Test all connections by brushing on an approved non-
corrosive leak-detection solution. Bubbles will show a leak.
Correct any leak found.
At test pressures greater than ¹⁄₂ psig (3.5 kPa), the
furnace and the manual gas shutoff valve must be
disconnected from the gas supply piping system.
At test pressures less than or equal to ¹⁄₂ psig (3.5 kPa),
the furnace must be isolated from the gas supply piping
system by closing the manual gas shutoff valve.
14. Replace the burner access panel.
