Installation Instructions
The S-150 “Summeraire” Add-On wood burning furnaces
are assembled. Your installer will be required to do some
wiring.
Before Installation Check the Following:
1. Examine the chimney to insure that it has the capacity
and draft conditions to handle the furnace. This furnace
must be vented into (a) a masonry chimney conforming
to Provincial regulations or in the absence of such regu-
lations, to the requirements of The National Building
Code, OR local codes and regulations, OR (b) a factory
built chimney labelled THAT IT COMPLIES TO ULC
S629-M.
2. Do not connect this furnace to a chimney serving a gas
appliance.
3. An 8” connection into the chimney must be provided.
This 8” connection must be located below the connec-
tion into the chimney from any existing oil heating unit
only.
4. Check the proposed location for the furnace and make
sure that the furnace will not be in violation of any of
the minimum clearances from combustible materials.
5. a) The S-150 woodburning add-on unit is certified to be
used in conjunction with an existing oil fired furnace
having a firing rate of .75 GPH to .85 GPH (U.S.). This
unit is not certified for connection to any other units.
b) The S-150 woodburning add-on unit is certifed to be
used in conjunction with an existing gas fired furnace
having a gas input shown on the original nameplate,
between 112500 minimum and 132000 maximum
B.T.U.H. and 23-38°C (70-100°F) air temperature rise.
6. CAUTION: Maintain combustion air to both furnaces -
air starvation is dangerous.
7. A fresh air opening of at least 120 in. shall be provided.
This shall be the larger of the values required for open-
ings in CGA Standard CAN1-B149.1, installations code
for natural gas burning appliances and equipment, or
CAN1-B149.2, installation code for propane burning
appliances and equipment, for tight structures, or that
required by C.S.A. Standard CAN3-B365, installation
code for solid fuel burning appliances equipment.
8. CERTIFIED FOR SERIES CONNECTION TO THE
OUTLET ONLY OF AN EXISTING OIL OR GAS
FIRED FURNACE.
9. If series method of interconnecting duct is used and
the existing oil or gas furnace is equipped with plenum
mounted fan limit control, the divider panel which you
install must be a minimum of 5” above the fan limit
control element casing. Divider panel must be reason-
ably air-tight.
10. Series method of interconnecting duct should only be
considered if the “Inline” flow installation cannot be
made.
11. Air flow through existing furnace shall be determined
before any changes are made to system:
1.Run oil or gas furnace at least 10-15 minutes or until
furnace has come up to maximum temperature.
2. Using thermometers determine temperature in R.A.
entering furnace and temperature in S.A. plenum. Tem-
perature rise through furnace is determined by subtract-
ing the temperature in R.A. plenum from temperature
in S.A. plenum. Temperature rise should be a maximum
85°F or that specified by manufacturer of furnace.
* There can be long lags in obtaining readings on ther-
mometers. The thermometers should be checked by ob-
serving the time required for correct temperature indica-
tion when they are immersed in boiling water.
Note: Accurate and “Easy to Read” dial thermometers are
to be used, with a minumum insertion of 12”.

12. The operation of the gas furnace must be verified for
acceptable operation before and after installation of the
add-on appliance by a gas fitter that is recognized by
the regulatory authority.
13. Do not connect to any gas furnace that has not been
certified initially as complying to CGA Standard
CAN1-2-3-M84 or its precedents.
