8.1.3  The terminal outlet (PN 60 50712 300) of thick 

wall aluminium pipe supplied must be fitted in 

a  horizontal  plane  and  be  placed  so  as  to  fit 

exactly between the elbow on the combustion 

fan  and  the  outlet  terminal  hole  with  sealing 

ring. 

 

 

If required this terminal  outlet must be  cut to 

length  in  order  to  respect  the  dimension 

75.0mm (fig. 8). 

However,  when  the  depth  of  the  control 

compartment exceeds the value E indicated in 

table  2,  a  seamless  duct 

100  or 

130  of 

thick wall aluminium and a sealing ring are to 

be  used  to  extend  the  length  of  the  terminal 

outlet  (PN  60  50712  300).    The  absolute 

maximum  allowable  extension  to  the 

protection  cap  (standard  length  300mm)  is 

700mm. 

 

8.1.4  Attention  must  be  given  to  properly  seal  the 

controls  compartment  from  the  enclosure  for 

the main air stream (duct channel).   

 

This  sealing  should  be  appropriate  to  avoid 

any leakage of air from controls compartment 

into the duct channel and vice versa. 

 

NOTE:  FLUE  ARRANGEMENTS  OTHER  THAN 

THOSE DESCRIBED AND SUPPLIED WITH THE 

HEATING MODULE ARE NOT PERMITTED 

 

8.1.5  A gas service inlet (PVC) sealing ring is also 

provided  for  the  appliance  for  size  Rc  3/4  or 

size Rc 5/4.  

 

The hole size required for the seal ring in the 

casing  is  50  or  75  mm  diameter.    The 

provided  sealing  ring  fits  for  1mm  thick 

panels. 

All  cables  and  wires  passing  through  the 

casing  of  the  burner/controls  section  should 

be 

via 

strain 

relief 

bushings.  

It  is  recommended  that  sealing  is 

accomplished  by  the  use  of  the  sealed  ring 

type. 

Connections  between  the  burner  module 

controls  compartment  must  be  effectively 

sealed  from  the  appliance  air-stream  so  the 

pressure  within  the  compartment  remains 

neutral.

9.1.1  The DJL Modules are provided with flue 

outlets sized as per table 4:

9.1.2  If  the  DJL  model  is  to  be  installed  as  a 

room sealed type C12 or C32 appliance, 

the burner and controls cabinet must be 

sealed so as to ensure air leakage does 

not exceed that stated in table 5. 

 

9.1.3  The  heating  modules  are  delivered  with 

all  parts  necessary  to  properly  seal  the 

combustion circuit. 

Included with the heating module are: 

 

-  90° elbow with sealing ring 

 PN 60 50733 130 (dia 130) or PN 60 

50733 100 (dia 100)

  gas tube sealing ring  

   

  (PN 06 22783 125) (3/4”) or PN 06  

   

  22783 054 (1 ¼”) 

-  2 ‘teflon’ sealing rings 

 

PN 06 22786 134 (dia 130) or PN 06 

22786 104 (dia 100) 

 

As  shown  in  figure  11a  these  sealing 

rings must be fitted in the outer casing to 

properly  seal  around  the  combustion  air 

inlet  pipe  and  the  flue  outlet  pipe.  The 

centre  distance  between  the  pipes  must 

be respected as per table 6 and the flue 

outlet  must  always  be  above  the 

combustion air inlet. 

Figure  11b  indicates  the  hole  size 

required  (as  shown  in  table  6)  in  the 

outer  casing  and  the  position  of  these 

holes  relative  to  the  mounting  flange  of 

the RHC 8000(M) DJL heating module.
