Model HF85R 7
WATER HEATING COIL (MODEL SHW4)
ARDENT ENERGY heating units are designed to heat your do-
mestic hot water during the heating season.
The HF85R can accept one or two coils (1 per side). The coil
replaces all but one of the firebrick on the side located.
Procedure:
NOTE:
Ensure installation complies with local plumbing codes.
1. Remove both side shrouds by unscrewing the
screws at back.
2. Remove rear heat shield and punch out the 2
knockouts on the side desired. Knock outs are
tight, out of necessity. A sharp blow with a heavy
hammer will be required.
3. Loosen cross draft angle nuts on side of unit. (2
each side located on outside of firebox).
4. Remove brick from that side.
5. Punch out 2 knockouts at back of stove. Reach in
through punched out holes with a bar extension
and punch out knockouts in primary heat ex-
changer. (see Fig 5.)
6. Position water coil in stove, replace brick and
tighten cross draft angle nuts on side of heater to
hold coil in place.
7. Install mineral wool gasket and plate on outside
and screw tight.
8. Replace shrouds and heat shield.
TANK CONNECTION
It is recommended that the ‘2 tank” system be used. The first
tank or “Range Boiler” must remain un-insulated to dissipate any
excess heat generated by the hot water coil.
Connection of piping to Range Boiler must be strictly followed as
shown in the Diagram. The 2 shut—off valves must be no smaller
than 3/4 inch GATE valves. Make certain that the PRV (Watts 3L)
and P&TRV (Watts 100XL) are installed in their respective loca-
tions and not vice versa. Maximum pressure setting is 150 psi.
Do not use less than 3/4 inch diameter standard pipe between
range boiler and heater, orientation of pipe must be slightly uphill
from the coil outlet to the upper connection at the tank, otherwise
vapor lock will occur and water will not circulate. Minimum range
Boiler recommended is 30 Imperial gallon capacity.
