11 Gas Information

A. Gas Pressure Requirements B. Gas Connection

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 dis- connected 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 pip- ing 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.

WARNING

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.

	Natural Gas		Propane
Inlet Gas Pressure	1.13	- 3.40 kPa	2.75 - 3.40 kPa
Outlet (Manifold) Gas	.80	- .95 kPa	2.36 - 2.61 kPa
Pressure
Max. Gas Consumption	26.7 mJ		24.5 mJ
Burner Injector	2.53 mm		1.45 mm
Burner Air Shutter	13 mm		11.5 mm

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

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: (Items 1, 2 and 3 applies to 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.

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

WARNING

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.
