Gas Information

A. Fuel Conversion
• Make sure the appliance is compatible with available gas
types.
• conversions must be made by a qualified service technician
using hearth & home technologies specified and approved
parts.
B. Gas Pressure
• optimum appliance performance requires proper input
pressures.
• gas line sizing requirements will be determined in aNSI
Z223.1 National Fuel gas code in the USa and caN/cga
B149 in canada.
• Pressure requirements are:

Gas Pressure

Minimum inlet pressure
Maximum inlet pressure
Manifold pressure
WARNING! Risk of Fire or Explosion! High pressure will
damage valve. Low pressure may cause explosion.
• Verify inlet pressures. Verify minimum pressures when
other household gas appliances are operating.
• Install regulator upstream of valve if line pressure is greater
than 1/2 psig.
!
Fire Risk.
Explosion Hazard.
High pressure will damage valve.
• disconnect gas supply piping BeFoRe
pressure testing gas line at test pressures
above 1/2 psig.
• close the manual shutoff valve BeFoRe
pressure testing gas line at test pressures
equal to or less than 1/2 psig.
Note: have the gas supply line installed in accordance with
local codes, if any. If not, follow aNSI 223.1. Installation
should be done by a qualified installer approved and/or
licensed as required by the locality. (In the commonwealth of
Massachusetts installation must be performed by a licensed
plumber or gas fitter).
Note: A listed (and Commonwealth of Massachusetts
approved) 1/2 in. (13 mm) t-handle manual shut-off valve
and flexible gas connector are connected to the 1/2 in. (13
mm) control valve inlet.
• If substituting for these components, please consult
local codes for compliance.

WARNING
C. Gas Connection
• Refer to Reference Section 3 for location of gas line access
in appliance.
• ensure that gas line does not come in contact with outer
wrap of the appliance. Follow local codes.
• connect incoming gas line to the 1/2 in. (13 mm) connection
on manual shutoff valve.
WARNING! Risk of Fire or Explosion! Support control
when attaching pipe to prevent bending gas line.
• a small amount of air will be in the gas supply lines.
WARNING! Risk of Fire or Explosion! Gas build-up during
line purge could ignite.
• Purge should be performed by qualified service
technician.
• Ensure adequate ventilation.
• Ensure there are no ignition sources such as sparks or
open flames.
light the appliance. It will take a short time for air to purge
from lines. When purging is complete the appliance will light
and operate normally.
WARNING! Risk of Fire, Explosion or Asphyxiation!
Check all fittings and connections with a non-corrosive
commercially available leak-check solution. DO NOT use
open flame. Fittings and connections could have loosened
during shipping and handling.
WARNING! Risk of Fire! DO NOT change valve settings.
This valve has been preset at the factory.
D. High Altitude Installations
NOTICE: If the heating value of the gas has been reduced,
these rules do not apply. Check with your local gas utility or
authorities having jurisdiction.
When installing above 2000 feet elevation:
• In the USa: Reduce input rate 4% for each 1000 feet above
2000 feet.
• In caNada: Input ratings are certified without a reduction
of input rate for elevations up to 4500 feet (1370 m)above
sea level. Please consult provincial and/or local authorities
having jurisdiction for installations at elevations above
4500 feet (1370 m).
check with your local gas utility to determine proper orifice
size.
