a) Properly install gas line to all local codes
b) Mount heaters using non-combustible mounting hardware
c) Observe all minimum clearances as indicated: OUTDOOR in Table 1 and Figure 1, page
7; INDOOR in Table 3 and Figure 3, page 10.
d) Suggested mounting distances for comfort in Table 2 and Figure 2 are guidelines based
on experience. Site conditions can allow for some deviation from these distances.
WARNING: When using Wall Mounting Bracket JP-2300-MB, or Arm Mounting Bracket JP-
2300-MK, ensure that anchoring to the structure is of sufficient strength, integrity
and workmanship, to support the weight of the heater and any other loads such
as snow.
e) Connect heater to the main gas line. An approved 1/2" flexible connector (field supplied -
available as an option from the manufacturer) must be used to absorb heater and gas line
expansion and any vibration - check local code requirements.
f) Check gas line for leaks by using soap test or gas meter test. Ensure gas pressure meets
the requirements outlined in Section 7.1 (above).
WARNING: When testing the main gas line pressure up to 0.5 psig, ensure that the isolation
valve and combination gas valve are "OFF", otherwise damage to the combina-
tion gas valve will result. When testing main gas line in excess of 0.5 psig the
appliance and shut off valve must be disconnected or isolated from the gas sup-
ply piping system during any such pressure testing. Gas supply to the heater
must be regulated to be maximum 0.5 psig (14”w.c.) and minimum values listed
in Table 3 above in Section 7.1
g) All wiring must comply to local and national codes. The heater requires 24Vac power sup-
ply. The heater system zone requires a field supplied 120/24Vac transformer rated at
40VA for the first heater plus 20VA for each additional heater in the zone. Ensure proper
electrical rating in the system by checking voltage at ignition module terminals. To avoid
system malfunction, the voltage range must be within 10% of required 24Vac (21.6 Volts
to 26.4 Volts), and correct polarity must be maintained throughout the system.
h) Test-fire the heating system by following the lighting instructions listed below and on the
heater label.
9. INSTALLATION PROCEDURES
PROPER WIRING POLARITY MUST BE MAINTAINED, particularly when grouping the heat-
ers in a zone. Total wiring distances of up to 200' must use minimum 16 gauge electrical wire,
and wiring distances of over 200' must use minimum 14 gauge electrical wire. The heater
must be electrically grounded in accordance with local and national electrical codes. Malfunc-
tion of the heating system will result if the voltage varies by more than ±10% .
The heater can be controlled by a line voltage thermostat, a 24 volt thermostat or “off-on”
switch. Total load of all heaters must be considered in determining the required contact rating
of the controlling thermostat or switch.
