Gas Information

A. Gas Pressure Requirements
Pressure requirements for RED40-N-AU, RED40ST-N-
AU fi replaces are shown in Table 11.1 below.
Two taps are provided on the front face of the gas control
for a test gauge connection to measure the inlet and out-
let pressures. See Figure 11.1.
The fi replace 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 3.40 kPa.
If the fi replace 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.
WARNING
Fire Risk
Explosion Risk
High pressure will damage valve.
• Disconnect gas supply piping BEFORE
pressure testing gas line at test pressures
above 3.40 kPa.
• Close the manual shutoff valve BEFORE
pressure testing gas line at test pressures
equal to or less than 3.40 kPa.

Columns highlighted in gray = The gas control valve supplied with this product is approved for a maximum
inlet pressure of 3.40 kPa. For pressures over 3.40 kPa, an in line pressure regulator must be installed
upstream from the gas control valve.

B. Gas Connection
Note: Have the gas supply line installed in accordance with
local building codes by a qualifi ed installer approved and/or
licensed as required by the locality.
Note: Before the fi rst fi ring 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 fi nished 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 fi nal connection to the gas heater.
3. ISOLATING SWITCH: Location within 1 metre
of fi replace, subject to mantelpiece etc. Check to
ensure it remains clear of any mantelpiece instal-
lation.
Leak test all gas line points and the gas control valve prior
to and after starting the gas appliance.
