4. If you touch ungrounded objects (recharge your body with

static electricity), firmly touch furnace again before touch-
ing control or wires.

5. Use this procedure for installed and uninstalled (un-

grounded) furnaces.

6. Before removing a new control from its container, dis-

charge your body’s electrostatic charge to ground to protect
the control from damage. If the control is to be installed in
a furnace, follow items 1 through 5 before bringing the
control or yourself into contact with the furnace. Put all
used AND new controls into containers before touching
ungrounded objects.

may also be used to prevent ESD damage.

INTRODUCTION

The Model 383KAV, Series H and J Furnace is available in sizes
44,000 through 154,000 Btuh input capacities.

The design of the upflow gas-fired furnace is CSA (A.G.A. and
C.G.A.) certified for natural and propane gas and for installation
on combustible flooring, in alcoves, attics, basements, closets, or
utility rooms. The furnace is factory-shipped for use with natural
gas. A factory accessory gas conversion kit, as listed on the
furnace rating plate is required to convert furnace for use with
propane gas. The design of this furnace line is not A.G.A. and
C.G.A. certified for installation in mobile homes, recreation
vehicles, or outdoors.

Before installing the furnace in the United States, refer to the
NFGC and NFPA 90B. For copies of the NFGC and NFPA 90B,
contact the National Fire Protection Association Inc., Battery-
march Park, Quincy, MA 02269; or for only the NFGC contact the
American Gas Association, 400 N. Capitol St., NW, Washington
DC 20001.

Before installing the furnace in Canada, refer to the NSCNGPIC.
For a copy of the NSCNGPIC, contact Standard Sales, CSA
International, 178 Rexdale Boulevard, Etobicoke (Toronto), On-
tario, M9W 1R3, Canada.

Installation must comply with regulations of serving gas supplier
and local building, heating, plumbing or other codes in effect in the
area in which installation is made. In absence of local building
codes, installation must conform with NFGC in the United States
and the NSCNGPIC and all authorities having jurisdiction in
Canada.

These instructions cover minimum requirements for a safe instal-
lation and conform to existing national standards and safety codes.
In some instances, these instructions exceed certain local codes
and ordinances, especially those that may not have kept pace with
changing residential construction practices. We require these
instructions as a minimum for a safe installation.

CAUTION:

Application of this furnace should be in-

doors with special attention given to vent sizing and
material, gas input rate, air temperature rise, and unit
sizing. Improper installation or misapplication of the
furnace can require excessive servicing or cause prema-
ture component failure.

NOTE:

These furnaces are designed for a minimum continuous

return-air temperature of 60°F or intermittent operation down to
55°F such as when used with a night setback thermostat. Return-air
temperature must not exceed a maximum of 85°F. Failure to
follow these return-air temperature limits may affect reliability of
heat exchangers, motors, and controls.
