I. Controls & Pex Pipe Connections
Boiler shown is set up as a single-zone. You
may install fittings to have ports for up to 4
zones
(Consult your dealer. Additional port setups with pumps
are also available from Nature’s Comfort when ordering a new unit.)
Single-Zone setup
1. Power from home feeds GFCI
2. Control power for pump, aquastat,
solenoid, blower and light is fed through
main plug by GFCI.
3. Switch for shutting off power to
aquastat (which will shut down blower &
solenoid).
4. Aqua-stat sensor for controlling blower
and solenoid.
5. Solenoid (behind cover) to lift intake
cover off blower.
6. Blower to feed oxygen to fire.
7. Damper to control air flow.
8. Pump to circulate water. (One pump is
included.)
9. Red Pex pipe goes from the pump to
heat exchanger(s) in home.
Please note!
The pump that came with your boiler may not be
the correct size for your installation. Please
consult your dealer for sizing as water flow is
essential to the proper & efficient operation of
your installation.
10. Blue Pex pipe returns from home to
upper port. (Use of additional valve is
recommended for ease of servicing. Not
included.)
11. Extra Port (This is for a low water cut-
off switch if required by an inspector.
Call an HVAC professional to install if
needed)
12. Wires to outdoor light.
J. Power Loss
The controls are also designed for the main control power plug to be used on a generator if
needed. If there is a loss of power and the water jacket starts to overheat from lack of circulation
first make sure to keep the water level full then use this feature if you have a generator to keep the
pump running. This typically is only a problem in milder weather. The remaining outlets have a
total of 10amps available to be used for additional pumps or convenience load if desired. Do not
load more than this as overloading of the supplying circuit will occur.
K. Insulated Pex Pipe
We highly recommend the use of insulated pex pipe for the best heat transfer possible from the
boiler to your home. 4” triple wrap & 5” foam insulated pipe is available for purchase through
Nature’s Comfort.
