VENTING 
NOTE: Planning for the venting system should be done in conjunction
with planning for the ductwork, drainage, and furnace accessories, such
as  air  cleaners  and  humidifiers.  Begin  assembling  the  venting  system
AFTER the furnace is set in place in the required orientation.
Venting  for  this  furnace  shall  follow  all  Local  codes  for  Category  IV
venting  systems.  This  furnace  is  CSA  approved  for  venting  with
PVC/ABS  DWV venting  systems. This  furnace  is  also  CSA  approved
for venting with M&G DuraVent

polypropylene venting systems using single wall straight and flex, and
required  fittings  (elbows,  reducers,  increasers,  connectors,  adapters)
only.
NOTE:  THESE  INSTRUCTIONS  DO  NOT  CONTAIN  DETAILED
INSTALLATION  INSTRUCTIONS  FOR  POLYPROPYLENE
VENTING  SYSTEMS.  Refer  to  the  polypropylene  venting  system
manufacturer’s  installation  instructions  for  the  polypropylene  venting
system installation.
NOTE:  When  using  polypropylene  venting  systems,  all  venting
materials used, including the vent terminations, must be from the same
manufacturer.
Special Venting Requirements for Installations in 
Canada
Installation in Canada must conform to the requirements of CSA B149
code.  Vent  systems  must  be  composed  of  pipe,  fittings,  cements,  and
primers  listed  to  ULC  S636.  The  special  vent  fittings,  accessory
concentric  vent  termination  kits,  (KGAVT0701CVT  or
KGAVT0801CVT) and accessory external drain trap available from the
furnace  manufacturer  have  been  certified  to  ULC  S636  for  use  with
those  Royal  Pipe  and  IPEX  PVC  vent  components  which  have  been
certified to this standard. In Canada, the primer and cement must be of
the same manufacturer as the vent system – GVS-65 Primer (Purple) for
Royal Pipe or IPEX System 636, PVC/CPVC Primer, Purple Violet for
Flue Gas Venting  and GVS-65 PVC Solvent Cement for Royal Pipe or
IPEX  System  636
(1)
t,  PVC  Cement  for  Flue  Gas Venting,  rated  Class
IIA,  65  deg  C.  must  be  used  with  this  venting  system  -  do  not  mix
primers and cements from one manufacturer with a vent system from a
different manufacturer. Follow the manufacturer’s instructions in the use
of  primer  and  cement  and  never  use  primer  or  cement  beyond  its
expiration date.
The safe operation, as defined by ULC S636, of the vent system is based
on  following  these  installation  instructions,  the  vent  system
manufacturer’s  installation  instructions,  and  proper  use  of  primer  and
cement. All fire stop and roof flashing used with this system must be UL
listed material. Acceptability under Canadian standard CAN/CSA B149
is  dependent  upon  full  compliance  with  all  installation  instructions.
Under this standard, it is recommended that the vent system be checked
once a year by qualified service personnel.
The  authority  having  jurisdiction  (gas  inspection  authority,  municipal
building  department,  fire  department,  etc.)  should  be  consulted  before
installation to determine the need to obtain a permit.

Consignes spéciales pour l’installation de 
ventilation au Canada 
L’installation faite au Canada doit se conformer aux exigences du code
CSA  B149.  Ce  systême  de  ventillation  doit  se  composer  de  tuyaux,
raccords, ciments et apprêts conformes au ULC S636.  La tuyauterie de
ventilation  des  gaz,  ses  accessoires,  le  terminal  concentrique  mural
(KGAVT0701CVT or KGAVT0801CVT) ainsi que l’ensemble du drain
de condensation extérieur fourni par le fabricant de cette fournaise ont
été certifiés ULCS 636 pour l’application des composantes Royal Pipe,
IPEX  PVC qui sont certifiées à ce standard. Au Canada, l’apprêt et le
ciment  doivent  être  du  même  fabricant  que  le  système  d’évacuation.
L’apprêt  GVS-65  (Purple)  et  le  ciment-solvant  GVS-65  doivent  être
utilisé  avec  les  Royal  Pipe.  Système  IPEX  636,  apprêt  PVC/CPVC,
Purple    pour  évacuation  des  gaz  de  combustion  et    système  IPEX
636(1)t, ciment PVC pour évacuation des gaz de combustion, coté classe
IIA, 65 deg C. doivent être utilisés avec le système d’évacuation IPEX
636 – Ne pas combiner l ’apprêt et le ciment d’un manufacturier avec un
système d’évacuation d’un manufacturier différent.
Bien  suivre  les  indications  du  manufacturier  lors  de  l’utilisation  de
l’apprêt et du ciment et ne pas utiliser ceux-ci si la date d’expiration est
atteinte.
L’opération  sécuritaire,  tel  que  définit  par  ULC  S636,  du  système  de
ventilation est basé sur les instructions d’installation suivantes, ainsi que
l’usage  approprié de l’apprêt et ciment.   Tout arrët  feu  et solin de  toit
utilisés  avec  ce  système  doivent  être  des  matériaux  listés  UL.
L’acceptation  du  standard  Canadien  CAN/CSA  B149  est  directement
relié à l’installation conforme aux instructions ci- haut mentionnées. Le
standard Canadien recommande l’ inspection par un personel qualifié et
ce, une fois par année.
Les  autoritées  ayant  juridiction  (inspecteurs  de  gas,  inspecteurs  en
bâtiments,  département  des  incendies,  etc)  devraient  être  consultées
avant l’installation afin de déterminer si un permis est requis.
