ACCESSIBILITY CLEARANCE, WHERE GREATER, SHOULD TAKE PRE-
CEDENCE OVER MINIM UM FIRE PROTECTION CLEARANCE. A gas-
fired furnace for installation in a residential garage must be in-
stalled so that the ignition source and burners are located not
less than eighteen inches (18") above the floor and is protected
or located to prevent physical damage by vehicles. A gas furnace
must not be installed directly on carpeting, tile, or other com-
bustible materials other than wood flooring.
FURNACE SUSPENSION
If suspending the furnace from rafters or joist, use 3/8" threaded
rod and 2”x2”x3/8” angle iron as shown below. The length of rod
will depend on the application and the clearances necessary.

EXISTING FURNACE REM OVAL
NOTE: When an existing furnace is removed from a venting system
serving other appliances, the venting system may be too large to
properly vent the remaining attached appliances.
The following vent testing procedure is reproduced from the
American National Standard/ National Standard of Canada for
Gas-Fired Central Furnaces ANSI Z21.47-Latest Edition, CSA-2.3-
Latest Edition Section 1.23.1. The following steps shall be fol-
lowed with each appliance connected to the venting system
placed in operation, while any other appliances connected to the
venting system are not in operation:
a. Seal any unused openings in the venting system;
b. Inspect the venting system for proper size and
horizontal pitch, as required by the National Fuel Gas
Code, ANSI Z223.1 or the CAN/ CSA B149 Installation
Codes and these instructions. Determine that there is
no blockage or restriction, leakage, corrosion and other
deficiencies which could cause an unsafe condition;
c. In so far as practical, close all building doors and
windows and all doors between the space in which the
appliance(s) connected to the venting system are
located and other spaces of the building. Turn on clothes
dryers and any appliance not connected to the venting
system. Turn on any exhaust fans, such as range hoods
and bathroom exhausts, so they shall operate at
maximum speed. Do not operate a summer exhaust fan.
