Section 9, Mounting the Space Heating Module (optional)
Figure 9-1 Space Heating Module Plumbing Fittings
When installing the Space Heating Module, see Figure 9-2: Space
Heating Module and Hot Water Heater Hookup, the following
instructions apply to the WaterHeater™ and the Space Heating
Module:
•
Install the cold water inlet tee (supplied) into the fitting labeled
cold water inlet located on the lower middle face of the
WaterHeater™ and tighten to a leak free condition. If the drain
valve has been previously installed on the WaterHeater™, the
domestic water pump must be disabled and the WaterHeater™
tank drained before the valve is removed and the cold water
inlet tee installed. Use two wrenches. Reinstall the drain valve
into the axial side of the newly installed tee and tighten to a
leakfree condition. Use a food safe Teflon tape on the fittings.
•
Remove the plastic plug on the WaterHeater™ front panel
labeled “Space Heating Module”. The hot water supply from
the WaterHeater™ to the Space Heating Module is a female
1/2” NPT fitting located behind the plug. This is to be
connected to the Hot Water In connection on the Space Heating
Module. Two male 1/2” NPT x 3/4” hose barbs (not supplied),
3/4” I.D. heavy duty rubber hose, and good quality hose
clamps are recommended for connecting the two fittings
together.
