A. GasPressureRequirements

Pressure requirements for XLR-PLUS-AU 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 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 3.4 kPa.
If the 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. 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.
Table11.1

B. GasConnection

Note:Have the gas supply line installed in acc ordance with
local building codes by a quali ed installer approved and/or
licensed as required by the locality.
Note:Before the rst 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.
WARNING
Fire Risk
Explosion Risk
High pressure will damage valve.
• Dis connect ga s s upply pipi ng BEFORE
pressure testing gas line at test pressures
above 3.4 kPa.
• Close the manual shutoff valve BEFORE
pressure testing gas line at test pressures
equal to or less than 3.4 kPa.

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 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 nal connection to the gas heater.
3. ISOLATING SWITCH: Location within 1 metre
of replace, subject to mantelpiece etc. Check to
ensure it remains clear of any mantelpiece instal-
lation.
