Venting

When an existing unit is removed from a venting system
servicing other appliances, the venting system may be
too large to properly vent the remaining attached appli-
ances.

The following steps shall be followed with each appli-
ance remaining connected to the common venting sys-
tem placed in operation, while the other appliances
remaining connected to the common venting system
are not in operation.

1. Seal any unused openings in the common venting

system.

2. Visually inspect the venting system for proper size

and horizontal pitch, as required in the National
Fuel Gas Code, ANSI Z223.1, or the CANCGA
B149 Installation Codes and these instructions. De-
termine there is no blockage or restriction, leakage,
corrosion and other deficiencies which could cause
an unsafe condition.

3. Insofar as is practical, close all building doors and

windows and all doors between the space in which
the appliances remaining connected to the com-
mon venting system are located and other spaces
of the building. Turn on clothes dryers and any
appliance not connected to the common venting
system. Turn on any exhaust fans, such as range
hoods and bathroom exhausts, so they will operate
at maximum speed. Do not operate a summer ex-
haust fan. Close fireplace dampers.

4. Follow the lighting instructions. Place the appliance

being inspected in operation. Adjust thermostat so
appliance will operate continuously.

5. Test for spillage at the draft hood relief opening

after 5 minutes of main burner operation. Use the
flame of a match or candle.

6. After it has been determined that each appliance

remaining connected to the common venting sys-
tem properly vents when tested as outlined above,
return doors, windows, exhaust fans, fireplace damp-
ers, and any other gas-burning appliance to their
previous conditions of use.

7. If improper venting is observed during any of the

above tests, the venting system must be corrected
and in accordance with the National Fuel Gas Code,
(ANSI Z223.1), and/or CAN/CGA B149 Installation
Codes and the venting tables provided with the unit.

If resizing any portion of the common venting system,
use the appropriate table in Appendix G, in the National
Fuel Gas Code, ANSI Z223.1 and/or CAN/CGA B149
Installation Codes or Exhibit J (Venting Tables - Cat-
egory I, Central Furnaces - Sizing of Venting Systems
Serving Appliances Equipped with Draft Hoods, Cat-
egory I Appliances, and Appliances Listed for Use with
Type B Vents).

VIII. Condensate Drain

Condensate Drain Connection

This unit has a built in trap - no external trap is required.

To avoid double trapping and an overflowing drain pan,
soft plastic drain lines are not recommended.
