INsTAllATION RequIReMeNTs

Introduction

Please read these instructions completely and carefully before install-

ing and operating the furnace.
MODELS HTL-D AND HTLV-D
Models HTL-D and HTLV-D are oil fired forced air up-flow furnaces 

with an output capacity range of 89,000 BTU/Hr. to 140,000 BTU/

Hr.

!

CAUTION

DO NOT USE GASOLINE, CRANK CASE OIL, OR ANY 

OIL CONTAINING GASOLINE.
FOR YOUR SAFETY:
DO NOT STORE OR USE GASOLINE OR OTHER 

FLAMMABLE VAPORS AND LIQUIDS IN THE VICIN-

ITY OF THIS OR ANY OTHER APPLIANCE.

All models are CSA listed, (NRTL/C) for use with No. 1 (Stove) and 

No. 2 (Furnace) Oil. Please refer to the tables on page 11 (Oil Burner 

Setups) of this manual for performance and dimensional data.
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. 
In the United States of America, the installation of the furnace and 

related equipment shall be installed in accordance with the regula-

tions of NFPA No. 31, 

Standard for the Installation of Oil-Burning 

Equipment

, as well as in accordance with local codes.

Regulations prescribed in the National Codes and Local regulations 

take precedence over the general instructions provided in this instal-

lation 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

The maximum hourly heat loss for each heated space shall be calcu-

lated in accordance with the procedures described in the manuals of 

the Heating, Refrigeration and Air Conditioning Institute of Canada 

(HRAI), or by other means prescribed, or approved by the local 

authority having jurisdiction. 
In the United States, Manual J. titled, "Load Calculation" published 

by the Air Conditioning Contractors of America, describes a suitable 

procedure for calculating the maximum hourly heat loss.

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.
The minimum installation clearances are listed in 

Table 1

.

HEAT EXCHANGER SUPPORT SCREWS

Before final placement of the furnace, the heat exchanger support 

screws should be removed (See 

Figure 1

). This may be preferable 

if the furnace rear panel will be inaccessible after installation. The 

screws must be removed if the heat exchanger needs to be removed 

from the cabinet.
