800SA/801SA: Installation, Start–Up, Operating and Service and Maintenance Instructions

Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

22

Inspections before the sale and at the time of installation will determine

the acceptability of the chimney or the need for repair and/or (re)lining.

Refer to the 

Fig. 30

 to perform a chimney inspection. If the inspection of

a previously used tile-lined chimney:

a. Shows signs of vent gas condensation, the chimney should be 

relined in accordance with local codes and the authority having 

jurisdiction. The chimney should be relined with a listed metal 

liner, Type-B vent, or a listed chimney adapter kit shall be used to 

reduce condensation. If a condensate drain is required by local 

code, refer to the current edition of NFGC NFPA54/ANSI 

Z223.1, Section 12.10 for additional information on condensate 

drains.

b. Indicates the chimney exceeds the maximum permissible size in 

the tables, the chimney should be rebuilt or relined to conform to 

the requirements of the equipment being installed and the 

authority having jurisdiction. 

A  chimney  without  a  clay  tile  liner,  which  is  otherwise  in  good

condition, shall be rebuilt to conform to current edition of ANSI/NFPA

211 or be lined with a UL listed metal liner or UL listed Type-B vent.

Relining with a listed metal liner or Type-B vent is considered to be a

vent-in-a-chase. 
If  a  metal  liner  or  Type-B  vent  is  used  to  line  a  chimney,  no  other

appliance shall be vented into the annular space between the chimney

and the metal liner.

APPLIANCE APPLICATION REQUIREMENTS 

Appliance operation has a significant impact on the performance of the

venting  system.  If  the  appliances  are  sized,  installed,  adjusted,  and

operated properly, the venting system and/or the appliances should not

suffer  from  condensation  and  corrosion.  The  venting  system  and  all

appliances  shall  be  installed  in  accordance  with  applicable  listings,

standards, and codes. 
The furnace should be sized to provide 100 percent of the design heating

load requirement plus any margin that occurs because of furnace model

size  capacity  increments.  Heating  load  estimates  can  be  made  using

approved  methods  available  from  Air  Conditioning  Contractors  of

America (Manual J); American Society  of Heating,  Refrigerating, and

Air-Conditioning  Engineers;  or  other  approved  engineering  methods.

Excessive oversizing of the furnace could cause the furnace and/or vent

to fail prematurely. When a metal vent or metal liner is used, the vent

must be in good condition and be installed in accordance with the vent

manufacturer’s instructions.
To prevent condensation in the furnace and vent system, the following

precautions must be observed: 

1. The return-air temperature must be at least 60°F (16°C)db except

for brief periods of time during warm-up from setback at no lower

than  55°F  (13°C)  db  or  during  initial  start-up  from  a  standby

condition.

2. Adjust the gas input rate per the installation instructions. Low gas

input rate causes low vent gas temperatures, causing condensation

and  corrosion  in  the  furnace  and/or  venting  system.  Derating  is

permitted only for altitudes above 2000 ft. (610 M).

3. Adjust the air temperature rise to the midpoint of the rise range or

slightly  above.  Low  air  temperature  rise  can  cause  low  vent  gas

temperature and potential for condensation problems.

4. Set  the  thermostat  heat  anticipator  or  cycle  rate  to  reduce  short

cycling. 

Air  for combustion  must not  be  contaminated  by  halogen  compounds

which  include  chlorides,  fluorides,  bromides,  and  iodides.  These

compounds  are  found  in  many  common  home  products  such  as

detergent, paint, glue, aerosol spray, bleach, cleaning solvent, salt, and

air freshener, and can cause corrosion of furnaces and vents. Avoid using

such  products  in  the  combustion-air  supply.  Furnace  use  during

construction  of  the  building could cause  the furnace  to  be exposed  to

halogen compounds, causing premature failure of the furnace or venting

system due to corrosion. 
Vent dampers on any appliance connected to the common vent can cause

condensation  and  corrosion  in  the  venting  system.  Do  not  use  vent

dampers on appliances common vented with this furnace. 

ADDITIONAL VENTING REQUIREMENTS

A 4” (101 mm) round vent elbow is supplied with the furnace. A 5-inch

(127 mm) or 6- inch (152 mm) vent connector may be required for some

model  furnaces. A  field-supplied  4-inch-to-5-inch  (101  -  127  mm)  or

4-inch-to-6-inch (101 - 152 mm) sheet metal increaser fitting is required

when 5-inch (127 mm) or 6-inch (152 mm) vent connector is used. See

Fig. 31

 

Fig. 43

 Venting Orientation for approved vent configurations. 

NOTE: 

Vent connector length for connector sizing starts at furnace vent

elbow. The 4-inch vent elbow is shipped for upflow configuration and

may be rotated for other positions. Remove the 3 screws that secure vent

elbow to furnace, rotate furnace vent elbow to position desired, reinstall

screws. The factory-supplied vent elbow does NOT count as part of the

number of vent connector elbows. 

The vent connector can exit the furnace through one of 5 locations on the

casing. 

1. Attach the single wall vent connector to the furnace vent elbow, and

fasten  the  vent  connector  to  the  vent  elbow  with  at  least  two

field-supplied, corrosion-resistant, sheet metal screws located 180°

apart.

NOTE: 

An  accessory  flue  extension  is  available  to  extend  from  the

furnace elbow to outside the furnace casing. See Product Data Sheet for

accessory listing. If flue extension is used, fasten the flue extension to

the vent elbow with at least two field-supplied, corrosion-resistant, sheet

metal screws located 180° apart. Fasten the vent connector to the flue

extension with at least two field-supplied, corrosion resistant sheet metal

screws located 180° apart. 

2. Vent  the  furnace  with  the  appropriate  connector  (see

 

Fig. 31

 

-

Fig. 43

).

3. Determine the correct location of the knockout to be removed.
4. Use a hammer and screwdriver to strike a sharp blow between the

tie points and work  the  slug  back  and forth until the slug breaks

free.

CAUTION

!

BURN HAZARD

Failure to follow this caution may cause personal injury.

Hot  vent  pipe  is  within  reach  of  small  children  when  installed  in

downflow position. See the following instruction.

CAUTION

!

CUT HAZARD

Failure to follow this caution may result in personal injury.

Sheet metal parts may have sharp edges or burrs.  Use care and wear

appropriate  protective  clothing,  safety  glasses  and  gloves  when

handling parts and servicing furnaces.
