BOILER INSTALLATION

THIS BOILER MUST BE INSTALLED BY A QUALIFIED INSTALLER.

To insure the boiler is on a level foundation and above any possible dampness, a concrete pad is
recommended. The ash pit and boiler are then set on this pad. We recommend a layer of split firebrick
be placed in the bottom as shown in diagram 1. The cracks between the ash pit and boiler should be
sealed with a substance such as refractory cement in order to allow the unit to operate at peak efficiency.

Flue pipe must be a minimum of 26 gauge material. Every 90º elbow gives approximately the same
resistance as 10 feet of pipe so install as close to the chimney as possible so that a minimum of pipes
and elbows may be used. This will promote better draft and reduce creosote build up.

For the combination unit, install the oil burner box and oil burner (remove the plate and cut square
opening in gasket). This is illustrated in diagram 3.

Install controls, draft fan, etc. as shown in diagram 15 and connect wiring as shown in diagram 7, 8, 9, 10,
11A, 11B, or 12.

Suggested piping is illustrated in diagrams 13A, 13B, 14A & 14B.

If boiler is used as a wood boiler alone, connect in conventional way.

For the combination unit the installation must conform with the regulations of the local authorities having
jurisdiction with the applicable Electrical Code, and with the regulations in C.S.A. Standard B139, B365
and according to N.F.P.A. #31 “Standards for the Installation of Oil Burning Equipment,” and the National
Electrical Code N.F.P.A. #70.

Wood storage should conform to local bylaws.

This unit is not for use in mobile homes.

This boiler must be connected to a chimney flue with a minimum inside dimension of 8” x 8” square or 8”
round. No other appliance should be connected to this chimney flue. The chimney must be approved for
wood burning appliances. Do not use a flue pipe damper with this unit. The flue pipe connections must
be secured with metal screws and have as few elbows as possible.

IMPORTANT

he Boiler system must include both a dump zone to relieve excess operating capacity and a safety

gravity feed zone that operates to reduce excessive boiler temperatures during EMERGENCY POWER
FAILURES. These two (2) individual operating requirements can be achieved as either a single (1) zone
or multiple zones.

These zones must have the ability to dissipate at least 10% of the rated boiler

capacity.

The Boiler must be installed on a closed system

and

must be grounded. This

Boiler must have corrosion inhibitor in the water and an air separator must be
used to eliminate air in the Boiler System.

LOW WATER CUT-OFF

A low water cut-ff (LWC) control must be installed to guard against low water situations. A ¾” NPT
tapping is provided to mount this control directly on the front of the boiler. The low water cut-off control
can alternately be mounted on the ¾ NPT coil plate tapping if equipped. For mounting on other locations,
follow the LWC manufacturer’s instructions. The LWC control side must be wired in series with the load
side (labeled R) of the dump zone, aquastat #3. Make sure the LWC control’s source power is not
deenergized by the dump zone aquastat. See Diagram #8B & 15.
