Option 3: (Best but more hassle and messy) Purchase a tube of high temperature caulk from your
dealer or Nature’s Comfort and brush over the entire surface area of the rope seals to permanently
seal out smoke and creosote. Place a 2” strip of wax paper over this. Over-extend the latch open
and bounce the door/ash pan closed, then leave open to fully cure before starting a fire to get a
custom, long term seal.
NOTE! Adjust fuel door if you ever see any amount of smoke. See maintenance section.
Door adjustment is done at the factory but may be required again after installation and before
starting a fire as the seals compress over time.
See maintenance section for complete
adjustment and care instructions.
III. Heating Domestic Water, Pools and Spa’s
A. Sidearm or Plate Heat Exchanger For Domestic Hot Water
For a sidearm heat exchanger, the hot line from boiler must first go to the top side port. This creates
twice the domestic water flow through the sidearm as opposed to coming in at the bottom side port.
For the fastest recovery, install a small circulation pump on the domestic side that is controlled by a
strap-on thermostat or thermal snap disc placed on bottom line on the domestic side. Hookups to
the domestic side must be connected to the drain and pressure relief ports.
You cannot use a
sidearm if the pressure relief port is on top of the water heater tank. The domestic side will not
thermal siphon properly and will frequently air lock as well.
Make sure to keep drain & pressure relief in service & purge all air from piping and sidearm or it will
air lock.
The plate HX drawing shown is for a pre-heater setup. Leave utility energy on for this to maintain
the water temperature. As water is used it will then be heated by the plate HX for unlimited hot
water. You may also use a plate HX to bypass the water heater entirely for on-demand operation.
Always use a mixing valve to prevent scalding water temperatures.
