Location of unit
This unit meets the safe lighting performance criteria with
the gas manifold and control assembly provided, as specified
in the ANSI standards for gas-fired units and ANSI Z21.10.3/
CSA 4.3 - latest edition.
1. Maintain all clearances from combustible construction
when locating appliance. See Clearances from Combustible
Construction, this page.
2. Locate the appliance so that if water connections should
leak, water damage will not occur. When such locations
cannot be avoided, it is recommended that a suitable
drain pan, adequately drained, be installed under the unit.
The pan must not restrict combustion airflow. Under no
circumstances is the manufacturer to be held responsible
for water damage in connection with this unit, or any of its
components.
3. The appliance must be installed so that the ignition
system components are protected from water (dripping,
spraying, rain, etc.,) during appliance operation and service
(circulator replacement, control replacement, etc.,).
4. Appliances located in a residential garage and in adjacent
spaces that open to the garage and are not part of the living
space of a dwelling unit must be installed so that all burners
and burner ignition devices have a minimum clearance of
not less than 18" (46 cm) above the floor. The appliance
must be located or protected so that it is not subject to
physical damage by a moving vehicle.
5.
DO NOT
install this appliance in any location where
gasoline or flammable vapors are likely to be present.
6. The appliance must be installed on a level floor.
7. Combustible floor installation:
a. Models 502 - 752
require
an approved floor kit for
installation on combustible flooring (reference Table
1A).
b. Models 992 - 2072 are approved for installation
on combustible flooring without a floor kit.
Note:
Concrete block over wood flooring is not considered
non-combustible.
8. DO NOT install this appliance directly on carpeting or
other combustible material.
9. Maintain required clearances from combustible surfaces,
reference the
Indoor Clearances from Combustible
Construction Section
, this page.
10. For outdoor models, you must install an optional vent
cap. Instructions for mounting the vent cap are included
in the venting section of this manual. Do not install
outdoor models directly on the ground. You must install
the outdoor unit on a concrete, brick, block, or other
non-combustible pad. Outdoor models have additional
special location and clearance requirements. See Outdoor
Installation Venting, page 30. A wind proof cabinet
protects the unit from weather.

Note:
No additional clearance is needed on the right side of the
unit for the observation port. An observation port is located on
both the right and left side of the unit.
Maintain minimum specified clearances for adequate
operation. Allow sufficient space for servicing pipe
connections, pump and other auxiliary equipment, as well
as the unit. See rating plate for specific service clearance
requirements.

Although these units are CSA International design-certifi ed for
outdoor installations, such installations are not recommended
in areas where the danger of freezing exists. You must provide
proper freeze protection for outdoor installations, units installed
in unheated mechanical rooms or where temperatures may
drop to the freezing point or lower. If freeze protection is not
provided for the system, a low ambient temperature alarm is
recommended for the mechanical room. Damage to the unit by
freezing is non-warrantable.
