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
WARNING
Fire Risk.
Explosion Hazard.
High pressure will damage valve.
• Disconnect gas supply piping BEFORE
pressure testing gas line at test pressures
above 3.40 KPa (1/2 psig).
• Close the manual shutoff valve BEFORE
pressure testing gas line at test pressures
equal to or less than 3.40 KPa (1/2 psig).
WARNING! Risk of Explosion! An in-line regulator
MUST be installed if the gas pressure exceeds 3.4 kPa.
Failure to install a regulator could damage valve.
Pressure requirements for 6KX-AU fireplaces are shown
in the table below.
Two taps are provided on the right hand side of the gas
control for a test gauge connection to measure the inlet
and outlet pressures.
The fireplace and its individual shut-off valve must be dis-
connected from the gas supply piping system during any
pressure testing of the system at test pressures in excess
of 6 kPa.
If the fireplace must be isolated from the gas supply pip-
ing system by closing an individual shut-off valve, it must
be of the handle-less type.
• Optimum appliance performance requires proper input
pressures.
• 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 could cause explosion.
• Elongated pressure taps are recommended for gas
pressure testing on these models.
• Verify inlet pressures. Verify minimum pressures when
other household gas appliances are operating.
• Install regulator upstream of valve if line pressure is
greater than 3.40 KPa.

C. Gas Service Access
Note: This appliance does include a manual gas shutoff
valve that is located in the valve compartment. This manual
gas shutoff valve is accessible for service by removing the
decorative front. The valve is most accessible if it is located
forward in the control cavity of the appliance.
Depending upon local code, an additional manual gas
shutoff, in a readily accessible area may be required and
located upstream from the appliance.
D. Gas Connection
Note: Have the gas supply line installed in accordance with
local building codes by a qualified installer approved and/or
licensed as required by the locality.
Note: Before the first firing of the appliance, the gas supply
line should be purged of any trapped air.
Note: Consult local building regulations to properly size the
gas supply line leading to the (Rp 1/2 in.) hook-up at the unit.
Incoming gas line should be piped into the valve compart-
ment and connected to the ISO 7-Rp 1/2 (BSP Rp 1/2)
threaded gas inlet connection on the manual shutoff valve.
IMPORTANT NOTICE:
ALL Heat & Glo gas appliances)
1. 1/2 in. GAS LINE: Run through cavity 70 mm
above finished hearth level, NOT RIGID, NOT
CLIPPED, with minimum 500 mm into cavity and
120 mm back from plaster face.
2. PVC (COMPOSITE) GASLINE must terminate
minimum 500 mm short of gas heater. Copper pipe
MUST be the final connection to the gas heater.
3. ISOLATING SWITCH: Location within 1 metre
of fireplace, subject to mantelpiece etc. Check to
ensure it remains clear of any mantelpiece instal-
lation.
