Installation, Operation and Maintenance Instructions
GAS PIPING
1. (a) Floor Mounted Heaters
A minimum pipe diameter of 15mm is required for
inlet piping. A lever operated shut-off valve should
be installed within 1 metre of the appliance for
servicing the unit.
(b) Wall or Ceiling Mounted Heaters
Where it is not practical to install solid tube inside
the support bracket an AGA certified stainless steel
braided hose can be installed. This hose assembly
must comply with AS5601-2004 Gas Installations,
pipe sizing tables and shall not exceed 3 metres in
length. The internal diameter of the hose must not
be less than 15mm.
2. Check with local and state plumbing and heating codes
regarding sizing of the gas lines.
3. All gas pipe connections to the heater(s) must be sealed
with a gas pipe compound resistant to Natural Gas.
4. Installation of a drip leg if required in the gas supply line
going to each heater must conform to AS 5601.
5. When checking for gas leaks, do no use an open flame.
Use a soap and water solution and check for bubbles
indicating gas leakage.
6. Installation of 1/8” NPT plugged tapping, accessible for
test gauge connections, is required upstream of the gas
supply connection to the heater.
7. The heater must be permanently fixed on a level and
adequate footing. Attachment may be made utilising
the holes located in the heater base plate.
An AGA approved natural gas pressure regulator must be
installed in the pipeline at the base of the heater and be set
at 1 kPa.
Any modification to the heater not described in the
installation instructions may compromise the safety of this
appliance. Special concern is as follows:
(1)
DO NOT
shorten post length;
(2)
DO NOT
bypass thermocouple safety;
(3)
DO NOT
operate heater without a reflector;
Clothing or other flammable materials should not be hung
from the heater, or placed on or near the heater. The area
above the post may be extremely hot. Direct contact with
these metal surfaces should be avoided in order to prevent
burns or clothing ignition.
DO NOT locate either the gas or any electrical supply lines
directly over the top of the heater, as overheating
may occur.
The Heater must be installed in a location such that it is
readily accessible for servicing and have no restriction of
air flow to the air inlet of the heater’s casing.
