Install the burner and all wiring in accordance with the
National Electric Code ANSI/NFPA 70 (Canada CSA
C22.1) and all applicable codes and requirements. Wire
the burner in compliance with all instructions and dia-
grams provided by the appliance manufacturer. Verify
operation of all controls in accordance with the appliance
manufacturer's guidelines.
See Figure 9 for a typical wiring diagram, with the
RM7895A flame safeguard control, for reference purpos-
es only. Check the literature that was packaged with the
burner for the primary control manufacturer's instructions
and the exact wiring diagram for your specific burner.
Do Not Bypass Safety
Controls
Tampering with, or bypassing safety con=
trois could lead to equipment malfunction
and result in asphyxiation, explosion or
fire.
• Safety controls are designed and installed to pro-
vide protection.
• Do NOT tamper with or bypass any safety control.
• If a safety control is not functioning properly, shut off
all main electrical power and gas supply to the burn-
er and call a qualified service agency immediately.
Electrical Shock
Hazard
Electrical shock can cause severe
personal injury or death.
• Disconnect electrical power before installing or ser-
vicing the burner.
• Provide ground wiring to the burner, metal control
enclosures and accessories. (This may also be re-
quired to aid proper control system operation.)
• Perform all wiring in compliance with the Nation-
al Electrical Code ANSI/NFPA 70 (Canada CSA
C22.1)
Keep Service Access
Covers Securely
Installed
These covers must be securely in place to
prevent electrical shock, damage from ex=
ternal elements, and protect against injury
from moving parts.
All covers or service access plates must be in place
at all times except during maintenance and service.
This applies to all controls, panels, enclosures,
switches, and guards or any component with a cov-
er as part of its design.
