Figure 10 Condensate box arrangement

For double linear heaters refer to the relevant
SL data sheet. 

Effectively a DL heater comprises of two
identical SL heaters with the fan being
replaced by a condensate box and fan 
combined in one unit. 

Bracket positions, reflectors and turbulators
remain consistant with SL models. 

For total overall lengths and weights of DL
heaters refer to the table below. For damper
settings refer to the table on p11 section 11.

Installation should be carried out in the roof
space due to the length of the heaters. Refer
to the SL data sheet for bracket positions and
reflector installation.

Data is shown for all DL heaters.
