14. Do not connect to any furnace that is not equipped
with an air circulation blower.
IT IS VERY IMPORTANT TO ADHERE TO THE MINI-
MUM INSTALLATION CLEARANCES TO ENSURE A
SAFE INSTALLATION.
Installation
Before installation is started read and make sure that you
understand these instructions.
1. Inspect unit to ensure that it has not been damaged in
transit.
2. Remove electric controls and Instruction Envelope
shipped inside firebox.
3. Install plenums and ductwork in accordance with Duct
Diagram included in these instructions.
4. Do not connect duct work so that a reverse flow is
possible.
5. “BX” type cable used for wiring between existing oil
furnace and S-150 add-on, shall be installed with 1”
“stand-offs” to prevent it from coming in contact with
the S-150 casing.
6. The S-150 Summeraire add-on unit shall only be
installed on a furnace duct system and chimney which
are in good operating condition.
7. Do not use duct elbows having an inside radius of less
than 6”.
8. Do not relocate or bypass any of the safety controls in
the original furnace installation.
9. The blower in the oil or gas fired furnace shall not be
changed.
10. To obtain the required air flow or temperature rise
through the system, the blower and motor pulleys and
the blower motor may have to be changed. Current
flow through motor is to be maintained within name
plate rating.
11. Install Limit Control Bracket as shown on assembled
drawing using all holes provieded. Make sure this
bracket is installed on the upper front of casing, fur-
thest from interconnecting duct. Install the prewired
fan and limit Controls factory set at 280°F in hole
provided nearest side of furnace and install fan and
limit control Factory set at 200°F, in hole furthest from
side of furnace regardless of right of left hand location
of said mounting bracket.
12. Equipment shall be installed in a manner acceptable
to the Regualatory Authority and only by mechanics
experienced in such installations. When required by
the Authority, such mechanics shall be licensed.
13. A separate thermostat must be installed and a new
wire run to control this furnace.
Control Settings
Room Thermostat should be set in the 65°F to 70°F range.
Wood fan and limit control setting - 280°F (Factory Set)
Secondary oil limit control setting - 200°F (Factory Set)
Circulation fan blower off at 155°F (cuts in blower fan
when temperature is reached).
Circualtion fan blower off at 110°F (blower fan cuts out
when heat exchanger is cooled below this setting).
High limit cut out 280°F closes draft damper door when
heat exchanger reaches this temperature. Draft at chimney
should be between .05 and .08 inches water column.
The C.S.A. Certified Draft Regulator supplied must be
installed and set at .06” W.C.
WARNING
: If the draft regulator setting of .06 W.C. is
exceeded, it could cause a solid fuel fire to burn out-of-
control.
The damper door on the S-150 has an opening limited to
1/2” by a tab and screw arrangement. This is the maxi-
mum that this furnace is designed to fire at. Any tamper
-
ing of this will cause an out-of-control fire.
After Installation Check
Turn on electrical power to the unit. Set thermostat below
room temperature. The damper door should be shut.
Set thermostat higher than room temperature. Damper
door should be open.
Push in the button on the Honeywell fan limit control and
the circulation blower fan motor should come on. Return
the button to the auto position for firing.
