The heater can be mounted horizontally or up to an angle of 45º maximum from horizontal. When the heater 
is to be angle mounted adjacent to a sidewall, make sure the draft inducer assembly is on the lower side of 
the heater so that the control box access panel is easily accessible. Make sure the long axis of heater is level. 
Multiple  draft  inducer  positions  can  also  be  used  as  shown  in  the  diagrams.  This  allows  for  the  desired 
configuration of flue venting.

GAS CONNECTIONS AND REGULATIONS 

Tighten flexible gas hose and components securely.

Flexible metal gas hoses must be installed without any twists or

kinks in them. The hose will move during operation of the heater

and it can crack if it is twisted.
Failure to do so may result in death, serious injury or property

damage.

PORTANT BEFORE CONNECTING THE GAS TO THE HEATER    

1.

 

Connect to the supply tank or manifold in accordance with the latest edition of National Fuel Gas Code (ANSI 
Z223.1), and local building codes. Authorities having jurisdiction should be consulted before the installation 
is  made.  (In  Canada,  refer  to  the  latest  edition  of  CSA  Standard  B149.1,  Natural  Gas  and  Propane 
Installation Code.) 

2.

 

Check that the gas fuel on the burner rating plate matches the fuel for the application. 

3.

 

Check that the gas supply piping has the capacity for the total gas consumption of the heaters and any other 
equipment connected to the line.  

4.

 

Check that the calculated supply pressure with all gas appliances and heaters operating will not drop below 
the minimum supply pressure required for these heaters. Check inlet supply pressures on Section 12.0). 

5.

 

All  gas  supply  lines  must be  located  in accordance  with  the required clearances  to combustibles  from the 
heater as listed on the clearances label of the heater and Section 4.0) of this manual. 

6.

 

Pipe joint compounds must be resistant to the action of liquefied petroleum gases. 

7.

 

Tube  heaters  will  expand/contract  during  operation.  Where  local  codes  do  not  prohibit,  a  CSA  or  U.L. 
approved  flexible  connector  supplied  with  this  heater  is  required  for  connections  between  the  rigid  piping 
and the heater. A union should be installed before the control box inlet. An approved shut off valve should be 
installed within 6 feet of the union.  

8.

 

The gas pipe, flexible hose and connections must be self supporting. The gas pipe work must not bear any of 
the weight of the heater or any other suspended assembly.
