PLUMBING DIAGRAM FOR THERMO-SIPHON METHOD - MAX. DISTANCE 10 FT.
COIL INSTALLATION (See Coil Diagram on Page 14)
Place one of the nuts supplied on each leg of the coil. Place coil through the holes in the back of the firebox and adjust the nuts so
the pipes stick out about 1 1/4 to 1 1/2 inches from the side of the stove. Put flat washers and nuts on the outside and tighten
within 1/4 inch. Then place fiberglass rope around each pipe the washers and tighten. You are now ready to run pipes.
THERMO-SYPHON METHOD (LESS THAN 10 FEET)
This is the simplest and most economical method, however, the hot water tank must be less than ten feet from the stove. The water
inlet, where the temp./press./relief valve is located, must be higher than the top leg of the coil. The hot water tank should be ele-
vated, if necessary, to allow for proper thermo-siphon action (the method by which hot water will circulate automatically through
the system.)
a) Shut off the hot water heater and the old water supply to it. Drain the tank completely.
b) Remove the temp./press./relief valve and discard. Install a short 3/4" nipple and tee (1) along with a new temp./press./relief
valve.
c) Run 3/4" copper tubing along with the necessary fittings between the hot water tank and the top leg of the water coil. Install a
3/4" vent elbow and automatic “float type” air vent (2) in the high point of the line. Within two feet of the top leg of the water
coil install a 150 lb. pressure relief valve. (7) Run 3/4" tubing from the release exit of both relief valves downward (3) so the hot
water may escape the event of overheating.
d) Remove the drain valve at the bottom of the tank. Install a short 3/4" nipple and tee and re-install the drain valve to the tee (4).
Run 3/4" copper tubing with the necessary fittings between the drain/tee combination and the lower leg of the coil. After all of
the connections have been complete, you may refill the tank. Turn on the hot water heater only after the tank has been com-
pletely refilled.
