PG80VTLA: 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.

Most  states  in  the  USA  and  jurisdictions  in  Canada  have  laws  that
require  the  use  of  Carbon  Monoxide  (CO)  alarms  with  fuel  burning
products. Examples of fuel burning products are furnaces, boilers, space
heaters,  generators,  water  heaters,  stoves/ranges,  clothes  dryers,
fireplaces,  incinerators,  automobiles,  and  other  internal  combustion
engines. Even  if  there  are  no laws in  your jurisdiction requiring  a CO
Alarm, it’s highly recommended that whenever any fuel burning product
is used in or around the home or business that the dwelling be equipped
with  a  CO  Alarm(s).  The  Consumer  Product  Safety  Commission
recommends  the  use  of  CO  Alarm(s).  The  CO  Alarm(s)  must  be
installed,  operated,  and  maintained  according  to  the  CO  Alarm
manufacturer’s  instructions.  For  more  information  about  Carbon
Monoxide, local laws, or to purchase a CO Alarm online, please visit the

SAFETY CONSIDERATIONS 
Installing and servicing heating equipment can be hazardous due to gas
and electrical components. Only trained and qualified personnel should
install,  repair,  or  service  heating  equipment.  Untrained  personnel  can
perform basic maintenance functions such as cleaning and replacing air
filters.  All  other  operations  must  be  performed  by  trained  service
personnel. When working on heating equipment, observe precautions in
literature, on tags, and on labels attached to or shipped with furnace and
other safety precautions that may apply. 
These instructions cover minimum requirements 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  up  with  changing  residential  construction  practices.  We
require these instructions as a minimum for a safe installation. 
Wear  safety  glasses,  protective  clothing  and  work  gloves.  Have  fire
extinguisher  available  during  start-up  and  adjustment  procedures  and
service calls. 
This  is  the  safety-alert  symbol  . When  you  see  this  symbol  on  the
furnace  and  in  instructions  or  manuals,  be  alert  to  the  potential  for
personal injury. 
Understand  the  signal  words  DANGER,  WARNING,  and  CAUTION.
These words are used with the safety-alert symbol. DANGER identifies
the most serious hazards which will result in severe personal injury  or
death.  WARNING  signifies  a  hazard  which  could  result  in  personal
injury or death. CAUTION is used to identify hazards which may result
in minor personal injury or product and property damage. NOTE is used
to  highlight  suggestions  which  will  result  in  enhanced  installation,
reliability, or operation.
The  following additional  safety  considerations  should  be  followed  for
gas furnaces:
1. Use  only  with type of  gas approved for this furnace. Refer to the
furnace rating plate.
2. Install this furnace only in a location and position as specified in the
“Location” section of these instructions.
3. Provide  adequate  combustion  and  ventilation  air  to  the  furnace
space as specified in “Air for Combustion and Ventilation” section.
4. Combustion  products  must  be  discharged  outdoors.  Connect  this
furnace  to  an  approved  vent  system  only,  as  specified  in  the
“Venting” section of these instructions.
5. Never test  for gas leaks  with an  open  flame. Use  a  commercially
available soap solution made specifically for the detection of leaks
to check all connections, as specified in the “Gas Piping” section.
6. Always  install  furnace  to  operate  within  the  furnace’s  intended
temperature-rise  range  with  a  duct  system  which  has  an  external
static  pressure  within  the  allowable  range,  as  specified  in  the
“Start-Up,  Adjustments,  and  Safety  Check”  section.  See  furnace
rating plate.
7. When a furnace is installed so that supply ducts carry air circulated
by the furnace to areas outside the space containing the furnace, the
return  air  shall  also  be  handled  by  duct(s)  sealed  to  the  furnace
casing  and  terminating  outside  the  space  containing  the  furnace.
See “Air Ducts” section.
8. A  gas-fired furnace for installation in a residential garage must be
installed as specified in the warning box in the “Location” section.
9. The  furnace  may  be  used  for  construction  heat  provided  that  the
furnace  installation  and  operation  complies  with  the  first
CAUTION in the LOCATION section of these instructions.
10. These  Multipoise  Gas-Fired  Furnaces  are  CSA  (formerly A.G.A.
and C.G.A.) design-certified for use with natural and propane gases
(see  furnace  rating  plate)  and  for  installation  in  alcoves,  attics,
basements,  closets,  utility  rooms,  crawlspaces,  and  garages.  The
furnace is factory-shipped for use with natural gas. A CSA (A.G.A.
and  C.G.A.)  listed  accessory  gas  conversion  kit  is  required  to
convert furnace for use with propane gas.
11. See Fig. 2 for required clearances to combustible construction.
