WARNING!
Failure to install, operate or service this appliance in the approved manner may result in property
damage, injury or death. This heater must be installed and serviced by trained gas installation and
service personnel only.
The installation of this heater must conform with local building codes or, in the absence of such
codes, the CAN/CSA B149.1 and 2.
The gas outlet must be in the same room as the appliance and be accessible. It may not be concealed within or run
through any wall, floor or partition.
Install a sediment trap / drip leg if condensation may occur at any point of the gas supply line. This will
decrease the possibility of loose scale or dirt in the supply line entering the heater’s control system and
causing a malfunction.
Note:
High pressure gas above 14.0 W.C.P. (water column pressure) requires a high
pressure regulator and ball valve (field supplied).
A Stainless Steel Gas Connnector (field supplied) formed into a smooth C-shape is recommended (Figure
2.5). If local codes prohibit the use of a gas hose, then a swing joint may be used.
Attach the ball valve (field supplied) to the gas supply pipe. Apply pipe compound to NPT adapter threads to
seal the joint. Use only pipe compound resistant to liquid petroleum.
Note:
Provide a 1/8 in. NPT plugged tapping, accessible for test guage connection, immediately upstream of
gas connection to the heater (provided on ball valve, when supplied).
Attach a gas connector (field supplied) to the adapter and the heater’s gas inlet. Seal the joints.
Important!
The fittings (nuts) on the flexible connector (field supplied) must be connected to an adapter.
They may not be directly connected to the gas supply pipe.
Excessive torque on the manifold may misalign the orifice.
Always
use two wrenches to tighten mating pipe
connections.
Final assembly must be tested for gas leaks according to CAN/CSA B149.1 and 2 or local codes.
WARNING!
Testing for gas leaks with an open flame or other source of ignition may lead to fire or explosion and
cause serious injury or death. Test in accordance with CAN/CSA B149.1 and 2 or local codes.
To connect the gas:
To disconnect gas:
Disconnect the power to the heater.
Turn off the gas supply to the heater and “bleed” the gas line.
Using two wrenches, slowly loosen the fittings. Excessive torque on the manifold may misalign the orifice.
Inspect the hose and fittings for abrasion, wear or damage. Replace if necessary.
