6. Installation
6.1 Installation Overview
The installation of your new Unit Heater requires a few easy-to-follow steps.
These steps are described below. You will need to gather the required tools,
choose a suitable area for locating the heater, install either hanging mounts or
a floor support mount for the heater, install the flue system and flue pipe,
connect the gas supply, install the power cord and thermostat to the heater
control box, and test the heater.
This manual provides a general description of the flue pipe installation in
Section 6.5. It is recommended that the flue be installed by a trained
experienced service technician. The heater mounting requires advanced
planning. For example, if a mounting frame or support is required, this will
need to be constructed and installed in advance. It is recommended that
electrical outlets be installed by a certified electrician.
6.2 Tools Required
Adjustable Wrench
Hammer or Drill to Install Screw Hooks in Ceiling
¼” Nut Driver
Pipe Glue
Gas Leak Testing Solution (A soap and water solution works well).
6.3 Receiving and Unpacking
Your heater is shipped completely assembled except for the power cord and
thermostat which you will have to attach to the control box. Unpack the
heater and check for any shipping damage. If you suspect shipping damage,
contact your local Distributor.
6.4 Hanging Or Floor Mounting
In order to ensure proper ventilation and safety, the heater requires minimum
clearances of 6 inches from each side of the heater, a minimum of 6 inches
from the top of the heater, 18 inches from the back of the heater, and requires
6 inches from the flue pipe to adjacent surfaces. The heater must be
positioned so as to prevent contact within 10 feet of the hot air discharge from
the front of the heater. Choose a location of the heater which isolates heater
from accidental drafts and permits installation of a flue pipe (See Section 6.5;
See Section 1.2 Ventilation Requirements, page 1).
6.4.1 Hanging The Heater
Model 100 and Model 200 are designed to be suspended from the Top only.
Model 300 can be suspended from either the Top or the Bottom, as desired.
To prepare the heater for hanging, you will have to install threaded hooks,
eyebolts, or rods into the mounting holes of the heater. Locate the mounting

Part No. 4801-2987 Unit Heater 6
holes designed for receiving the hooks or rods. These hole locations are
labeled as H, I, and J in Section 5.1, page 4. For Model 300, there are ten
holes on the Top and ten holes on the Bottom which may be used to hang the
heater. The thread size of the mounting holes is 1/4-20.
The method of supporting the heater is the installer’s choice and
responsibility. Install the desired suspension supports into the ceiling. Make
sure that the ceiling supports are adequate to support the weight of the
heater. Screw the mounting holes of the heater appropriately threaded rods,
hooks, or eyebolts being used to attach cables or chains. Lift the heater into
position and suspend the heater on the previously installed ceiling supports.
Make sure to allow the required separation distances between the heater and
the ceiling and walls as described above and in Table 1.
6.4.2 Floor Mounting The Heater
If the heater is mounted on a floor stand, make sure that the stand has
sufficient strength to support the heater. Make sure that the heater is
securely attached to the stand, and that the heater and stand are not top-
heavy or unstable. It is recommended to secure a floor stand to the floor with
bolts. Be sure to construct the floor stand from non-combustible materials.
6.5 Flue Pipe Installation
Unit heaters must be vented in compliance with local codes, and within
standards of the American National Flue Gas Code, ANSI Z-223.1 or Canada
CAN/CGA-B149 installation codes. Flue gases are exhausted through the
exhaust blower on the rear of the heater, and must be vented to the outside of
the building through a flue system. The flue system is the responsibility of the
installer. It is recommended that the flue pipe be installed by an authorized
heater representative.
6.5.1 Flue Connector And Size Adapter
The exhaust blower must be coupled to the flue by attaching a flue connector
which is included with your heater. Attach the flue connector to the exhaust
blower as shown in Figure 1, page 7. Secure the flue connector with non-
corrosive screws. The flue connector output has a 4” diameter. A size
adapter must be attached to change diameters of the flue pipe. The size
adapter is not supplied with the heater. The size adapter is a metal vent pipe
which transitions from a 4” diameter to 5” diameter for Model 100, 6” diameter
for Model 200, or 7” diameter for Model 300. After attaching the flue
connector and size adapter, all seams and joints must be sealed with high
temperature jointing compound or jointing material such as aluminum tape.
Aluminum tape must meet the SMACNA AFTS-100-73 Standards. Silicone
rubber sealant must have a temperature rating of at least 400 degrees
Fahrenheit. All joints must be checked for tightness of fit after installation.

Part No. 4801-2987 Unit Heater 7
6.5.2 Flue Pipe
Refer to Figure 2, page 8. The flue is composed of short sections and elbows
of metal vent pipe joined together to connect the heater to the flue terminator
which extends to the outside of the building. The flue diameter is 4” for
Model 100, 5” diameter for Model 200, or 6” diameter for Model 300. All joints
and seams of the flue pipe must be sealed with high temperature silicon
rubber sealant or aluminum tape. The flue should be as short as possible
and have a minimum number of elbows. All joints must be secured by at
least two screws. After installation of the flue, check all joints for tightness.
Refer to National Standards NFPA 54/ANSI Z223.1 for U.S.A. or Canada
Standard CAN/CGA B149.1 and B149.2. If using a high temperature plastic
flue pipe (instead of metal), the first 18 inches of pipe extending from the flue
connector must be metal to prevent heat damage. The horizontally running
sections of the flue must normally maintain a slope of 1/4” rise per each foot
of horizontal run of the flue. The flue pipe should be supported with hangers
no more than 3 feet apart to prevent movement. Install a condenser tee and
drain within the first 5 feet of the heater. If a fume trap is used, be sure to
keep it filled with water.
The flue pipe must be 6 feet or more from an inside corner formed by two
exterior walls. If a single wall flue is used in an unheated area it should be
insulated with fiberglass to prevent excess condensation of flue gases.
If the flue pipe passes through a combustible wall, an insulating thimble
should be used (See Figure 2, page 8).
After passing through an outside wall, the flue pipe should be turned vertically
using an elbow. The vertically running segment of the flue pipe should be at
least 12 inches from the outside wall. The outside segment of the flue pipe
should extend vertically to at least 3 feet above the highest point of the roof
and should be terminated with a flue cowl.
