3. GAS PRESSURE
A pressure tap is included on the front face of the standing pilot gas control valve. The electronic valve includes a 1/8
NPT plugged tap on the top and bottom of the valve near the outlet to the main burner. Pressure taps are immediately
upstream of the gas supply connection and accessible for test gauge connection.
Table 2 shows optimum gas pressure information.
Consult your local gas company for assistance in determining the proper orifice for your altitude or refer to ANSI
Z223.1-latest edition, Appendix F.

Table 2
Gas Information for Electronic and Standing Pilot Appliances
Note:
This appliance and its manual shutoff
valve must be disconnected from the gas sup-
ply piping system during any pressure testing
of that system at test pressures in excess of
1/2 psi (3.5 kPa). The appliance must be iso-
lated from the gas supply piping system by
closing its manual shutoff valve during any
pressure testing of the gas supply piping sys-
tem at test pressures equal to or less than 1/2
psi (3.5 kPa).
4. WIRING
Note:
This appliance must be electrically wired and
grounded in accordance with local codes or, in the
absence of local codes, with National Electric Code
ANSI/NFPA 70-latest edition or the Canadian Electric
Code CSA C22.1.
Note:
Optional Accessories Requirements: Wiring for
optional accessories should be done now to avoid
reconstruction.
CAUTION:
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and
dangerous operation. Verify proper operation after
servicing.
WARNING!
This standing pilot appliance DOES NOT require a
110V AC supply for operation. Connecting the
appliance wall switch wires to 110V AC supply will
cause the appliance to malfunction and destroy the
valve and thermopile.
a. Standing Pilot
This standing pilot appliance does not require a
110V AC supply to operate. It is suggested that a
110V junction box be installed with a switched
outlet for the optional fan and an always-powered
outlet for the optional remote control.
Only heater listed appliances may be connected
to a thermostat (not supplied). Use a thermostat
that is compatible with a millivolt gas valve. See
Figure 28.
