Installation - Digital Control Wiring
1. Ensure the control installation is within the following application and
operating parameters:
• Ambient temperature from 38° to 125°F.
• Relative humidity ranging from 20% to 90% (non-condensing).
• Boiler load rating up to 15A resistive, 1/4hp inductive @ 120VAC.
• Circulator load rating up to 15A, 1/4hp inductive @ 120VAC.
• Space heating load rating up to 8A @ 120VAC.
NOTE: Line-voltage and safety-circuit wiring that is external to the
water heater jacket when all panels are in place, and which is part of
the appliance, shall be protected by metal conduit, metal-clad cable or
raceways. Thermoelectric wiring shall be exempt from this provision.
NOTE: Strain relief shall be provided for all conductors leaving an
enclosure. For low-voltage wiring, strain relief at the point of exit from an
enclosure is not necessary if, by wire location or support, protection is
provided against accidental strain.
