Note:
The appliance and its manual
shutoff valve must be disconnected from
the gas supply 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 isolated from the
gas supply piping system by closing its
manual shutoff valve during any pressure
testing of the gas supply piping system at
test pressures equal to or less than 1/2
psi (3.5 kPa).

Pilot Appliances

Figure 26 - Control Access Panel Removal
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.
4. WIRING
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.
Figure 28 - Standing Pilot Ignition Wiring Diagram
3. GAS PRESSURE
On both the standing pilot and the electronic ignition
gas valves, the inlet pressure and a manifold (outlet)
pressure tap are available on the face of the valve.
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 you
altitude or refer to ANSI Z223.1-latest edition,
Appendix F.
