IMPROPER INSTALLATION MAY 
CREATE A CONDITION WHERE THE 
OPERATION OF THE PRODUCT 
COULD CAUSE PERSONAL INJURY 
OR PROPERTY DAMAGE. 

IMPROPER INSTALLATION, 
ADJUSTMENT, ALTERATION, 
SERVICE OR MAINTENANCE CAN 
CAUSE INJURY OR PROPERTY 
DAMAGE. REFER TO THIS MANUAL 
FOR ASSISTANCE OR ADDITIONAL 
INFORMATION, CONSULT A 
QUALIFIED INSTALLER, SERVICE 
AGENCY OR THE FUEL SUPPLIER. 

 

 

THIS PRODUCT MUST BE INSTALLED 
IN STRICT COMPLIANCE WITH THESE 
INSTALLATION INSTRUCTIONS AND 
ANY APPLICABLE LOCAL, STATE, 
AND NATIONAL CODES INCLUDING 
BUT NOT LIMITED TO: BUILDING, 
ELECTRICAL AND MECHANICAL 
CODES. 

 

 

The furnace area must not be used as a 
broom closet or for any other storage 
purposes, as a fire hazard may be 
created. Never store items such as the 
following on, near or in contact with the 
furnace: 

1. Spray or aerosol cans, rags, 

brooms, dust mops, vacuum 
cleaners or other cleaning tools. 

2.  Soap powders, bleaches, waxes or 

other cleaning compounds; plastic 
items or containers, gasoline, 
kerosene, cigarette lighter fluid, dry 
cleaning fluids, or other volatile 
fluids. 

3.  Paint thinners or other painting 

materials and compounds. 

4.  Paper bags, boxes, or other paper 

or cardboard products. 

Never operate the furnace with the 
blower door removed. To do so could 
result in serious personal injury and/or 
equipment damage. 

 

 

DO NOT USE GASOLINE, 
CRANKCASE OIL, OR ANY OTHER 
OIL CONTAINING GASOLINE AS A 
FUEL FOR THIS FURNACE. 

INTRODUCTION 

Please read these instructions 
completely and carefully before installing 
and operating the furnace. 

The furnace must be installed and set up 
by a qualified contractor. 

Model WML-C is an oil fired forced air 
multi-positional furnace, with an output 
capacity range of 58,000 BTU/Hr. to 
85,600 BTU/Hr. The MPL-B is also an oil 
fired forced air multi-positional furnace 
with an output capacity range of 85,500 
BTU/Hr. to 123,000 BTU/Hr.  The WML-
C AND MPL-B furnace may be installed 
in the down-flow position, as well as both 
left and right horizontal positions. 

All models are listed with the 

Canadian 

Standards Association

, (CSA), and 

comply with the standards of both the 
United States and Canada for use with 
No. 1 (Stove) and No. 2 (Furnace) Oil. 

In the United States, the installation of 
the furnace and related equipment shall 
be installed in accordance with the 
regulations of NFPA No. 31, 

Installation 

of Oil Burning Equipment

, as well as in 

accordance with local codes. 

In Canada, the installation of the furnace 
and related equipment shall be installed 
in accordance with the regulations of 
CAN/CSA - B139, 

Installation Code For 

Oil Burning Equipment

, as well as in 

accordance with local codes. 

When installation or application 
questions arise, regulations prescribed in 
the National Codes and Local 
Regulations take precedence over the 
general instructions provided with this 
installation manual. When in doubt, 
please consult your local authorities.  

All models are shipped assembled and 
pre-wired. The furnace should be 
carefully inspected for damage when 
being unpacked. 

HEAT LOSS 

To determine the correct furnace and 
firing rate for an application, it is 
necessary to calculate the maximum 
hourly heat loss of the building based on 
local design conditions. In new 
construction, the heat loss should be 
calculated on a room-by-room basis to 

enable proper sizing of the trunk and 
branch ductwork. In retrofit applications, 
a building shell (overall) heat loss 
calculation may be used. 

In the United States, Manual J. titled, 
"Load Calculation" published by the Air 
Conditioning Contractors of America, 
(ACCA), describes a suitable procedure 
for calculating the maximum hourly heat 
loss. 

In Canada, the maximum hourly heat 
loss may be calculated in accordance 
with the procedures described in the 
manuals of the Heating, Refrigeration 
and Air Conditioning Institute (HRAI), or 
by other method prescribed by 
authorities having jurisdiction that are 
suitable for local conditions. 

LOCATION OF UNIT 

The furnace should be located such that 
the flue connection to the chimney is 
short, direct and consists of as few 
elbows as possible. When possible, the 
unit should be centralized with respect to 
the supply and return air ductwork. A 
central location minimizes the trunk duct 
sizing. All models may be installed on 
combustible floors. Do not install the 
furnace on carpet or tiled floors. 

Minimum installation clearances are 
listed in Table 1. 

NOTE

: The recommended installation 

clearances do not necessarily take into 
consideration the clearances necessary 
to replace the air filter or perform other 
routine maintenance. 

DOWN-FLOW INSTALLATION 

All WML-C AND MPL-B furnace models 
have been assembled for installation in 
the down-flow position. Maintain all 
clearances to combustibles as outlined in 
Table 1. 

Suggestion

; as a measure to 

prevent fuel oil from accumulating in 
locations other than the fire pot, as could 
be the case in the event of nozzle drip, 
install the furnace with an approximate 2 
degree slope from the oil burner casing 
towards the fire pot. Use shims made of 
noncombustible material.
