Operating Instructions and Owner’s ManualEnerco | Compact Unit Heater
These units are approved for residential applications. For installation in a
residential garage, these units must be installed so that burners and
ignition
source are located no less than 18” (457mm) above floor. Heater
must
be located or protected to avoid physical damage by vehicles.
Refer to CSA B149.1, Natural Gas and Propane Installation Code current
edition
.
In
a confined area, the heater must be installed in accordance with the
CSA B149.1, Natural Gas and Propane Installation Code. Be sure to check
with
local codes and ordinances for additional requirements.
UNIT HEATER INSTALLATION
Unit is shipped ready for installation. Unit may be installed
as sh
own in
figure
1
or inverted 180
o
depending on desired location
as
governed by clearances, vent connection, air direction, gas
suppl
y, electrical supply and service accessibility.
1. If installing unit in an inverted position: Remove and retain screws
securing
door and rotate door 180
o
. Secure with retained screws.
Rotate louvers directing airflow as desired.
2. Choose location for mounting brackets.
3. Remove and retain three screws along top edge (bottom edge
when
inverted) of front of unit.
4. Align screw holes on mounting bracket with holes along top edge
(either
upright or inverted) of unit. Secure one mounting bracket
to
front of unit with retained screws. Secure other mounting
bracket
to back of unit with screws provided in bag assembly
containing flue transition.
5. To support unit, secure mounting bracket to ceiling joist or truss.
Unit
may also hang on rods as shown in
figure

Natural Gas and Propane Installation Code in Canada,
or
applicable provisions of local building codes.
All
gas fired appliances require air to be used for the combustion
process. In many buildings today, there is a negative indoor air
pressure caused by exhaust fans, etc. If sufficient quantities of
combustion
air are not available, the heater or another
appliance
will operate in an inefficient manner, resulting in
incomplete
combustion which can result in the production of
excessive carbon monoxide.
CAUTION Insufficient combustion air can cause headaches,
nausea,
dizziness, asphyxiation or death.
If
indoor air is to be used for combustion, it must be free of the
following substances or the life of the heat exchanger will be
adversely
affected: chlorine, carbon tetrachloride, cleaning solvent,
halogen
refrigerants, acids, cements and glues, printing inks,
fluorides,
paint removers, varnishes, or any other corrosives.
VENTING
A – GENERAL RECOMMENDATIONS AND
REQUIREMENT
S
NOTE: The vent is a passageway, vertical or nearly so, used to
co
nvey flue gases from an appliance, or its vent connector, to the
outside
atmosphere. The vent connector is the pipe or duct that
connects
a fuel-gas burning appliance to a vent or chimney.
Unit
heaters must be vented in compliance with all local codes or
requirements of the local utility, the current standards of the
(American)
National Fuel Gas Code, ANSI Z223.1 or (Canada) CSA
B149.1 Natural Gas and Propane Installation Code, and the
following
instructions.
A metal stamped/extruded transition is supplied with this certified
unit.
It must not be modified or altered and must be installed on
the
outlet of the induced draft blower assembly prior to the
install
ation of the vent or vent connector. Failure to comply with
this
requirement will void the certification of the unit by the
approval
agencies. All joints shall be secured with at least two
corrosion
resistant screws. All joints must be checked for gas
tightness
after installation.

Maximum length of vent connector not to exceed 30 ft. (9.1m).
The installation shall conform with local building codes or, in the absence
of local codes, with the
National Fuel Gas Code, ANSI Z223.1 /
NFPA 54 or the CSA B 149.1, Natural Gas and Propane
Installation Code.
The appliance and venting system is to be inspected once a year
by a qualified service agency.
Adequate facilities for supplying air for combustion and
ventilation must
be provided in accordance with the latest edition
of
section 5.3, Air for Combustion and Ventilation, of the
National Fuel Gas Code, ANSI Z223.1, in the U.S.A., CSA B149.1
