Gas Information

A. Gas Pressure Requirements
Pressure requirements for VRT-AUB 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
disconnected from the gas supply piping system during any
pressure testing of the system at test pressures in excess
of 6 mbar.
If the fireplace must be isolated from the gas supply piping
system by closing an individual shut-off valve, it must be of
the handle-less type.
WARNING! Risk of Explosion! An in-line regulator MUST
be installed if the gas pressure exceeds 3.7 kPa. Failure to
install a regulator could damage valve.

Fire Risk
Explosion Risk
High pressure will damage valve.
• Disconnect gas supply piping BEFORE
pressure testing gas line at test pressures
above 6 kPa.
• Close the manual shutoff valve BEFORE
pressure testing gas line at test pressures
equal to or less than 6 kPa.

An in-line regulator MUST be installed if the gas pressure
exceeds 3.40 kPa. Failure to install a regulator could
damage valve.

B. 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 compartment
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 installation.
Leak test all gas line points and the gas control valve prior
to and after starting the gas appliance.

CHECK FOR GAS LEAKS
Explosion Risk
Fire Risk
Asphyxiation Risk
• Check all fittings and connections.
• Do not use open flame.
• After the gas line installation is complete, all
connections must be tightened and checked
for leaks with a commercially-available, non-
corrosive leak check solution. Be sure to rinse
off all leak check solution following testing.
Fittings and connections may have loosened
during shipping and handling.
