Gas Supply Pressure
CAUTION
!
To avoid property damage, maximum gas supply
pressure must not exceed 14" WCP.
Appliance and individual shutoff valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of ½ psig (3.5kPa) (14" WCP).
Appliance must be isolated from gas supply piping
system by closing manual shutoff valve during any
pressure testing of the gas supply piping system at
test pressures equal to or less than ½ psig (3.5kPa)
(14" WCP).
Gas supply pressure for checking regulator setting
must be at least 1" WCP above manifold pressure
shown on rating label.
Duct Requirements
Duct should be 6-inch round metal ducting. Island or
peninsula installations may require 3
1
/4 X 10 inch duct.
To ensure proper ventilation, duct work must not exceed
60 equivalent feet.
Curved fittings should not account for more than 50% of
duct length.
Flexible duct is not recommended because of irregular
interior surface. If flexible duct is to be used, one foot is
equal to 2 feet of metal duct. NEVER USE PLASTIC
TYPE DRYER DUCTING.
Do not vent into an attic or crawl space. Vent range
outside.
Flexible duct elbows are equal to twice as many feet as
smooth metal elbows.
Never install two elbow fittings next to each other. Two
elbows installed together create a poor vent path and
insufficient ventilation.
Seal all duct joints tightly using duct tape. Openings left
in ducting allow smoke and odor to escape inside
house.
For best performance, do not use more than three 90°
elbows.
6-inch transition duct provided must be mechanically
secured to exhaust blower outlet. Secure transition duct
using two screws provided.
