Gas Line Installation; Thermostat Or Wall Switch Installation - Drolet GTX-I Installation And Operating Instructions Manual

3.3.2 Gas line installation

Install supply line using any piping approved for your installation meeting CAN/CGA 6.10, AA 3,
ANSI Z21.24 or Z21.45. A qualified gas fitter should install the gas line in accordance with all
local building codes. If codes permit, coiled copper tubing may be used for gas supply.
Pressure taps are provided on the gas control for test gauge connections to measure the manifold
and inlet pressures.
This appliance must be isolated from the gas supply piping system by closing its individual manual
shut off valve during any pressure testing of the gas supply piping system at test pressures equal
to or less than 1/2 psig (3.45 kPa).
The appliance 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 1/2 psig (3.45
kPa).
Install the gas line as follows:
The gas line connection found on the back of the valve is a 3/8" black iron nipple. An AGA and/or
CGA approved shut off valve can be installed in conjunction with the nipple if so desired.
Installing the shut off valve on the end of the nipple will allow quick accessibility.
Upon initial firing check manifold pressure at pressure tap located on the front of the control valve
(see Figure 2).
WARNING: Do not use an open flame to test for gas leaks.

3.3.3 Thermostat or wall switch installation

The burner control switch is located on the control panel. For your convenience, the unit can also be
operated by a thermostat, or a wall switch control. Millivolt thermostats are available from most
hearth dealers. Bedroom installations require the use of a wall thermostat.
NOTE: The thermostat or wall switch MUST be rated for millivolt use. Minimize
splicing in all millivolt wiring & solder all unavoidable splices.
3.3.3.1 Remote control installation
Please refer to instructions included with kit.
3.3.3.2 Thermostat or wall switch installation
1. Mount the thermostat or wall switch in the desired location and run "two conductor thermostat
wire" to the burner control switch (Figure 3). To bypass the burner control switch, run the wires
directly to the gas valve (Figure 4).
Purchase "two conductor thermostat wire", which is not provided, at any local supplier. The
gauge of thermostat wire will determine the maximum wire length and distance at which to locate
the thermostat or wall switch.
thermostat. Be aware that, as the length of wire increases, the probability of adequate operating
voltage decreases.
