APPENDIX 6: OPTIONAL FORCED AIR DISTRIBUTION KIT
INSTALLATION, 94-57110
It is possible to connect a forced air distribution kit* on either sides of this fireplace. Installing the
kit on the left side of the fireplace will provide better performances than on the right side.
This kit allows distributing heat to another room up to 50 feet (15 m) of the fireplace. The
insulated flexible pipe (not included in the kit) must be HVAC type pipe and must comply with
ULC S110 and/or UL 181, Class 0 or Class 1 Standards and must withstand temperatures up
to 250°F. For the complete installation procedure, see the installation manual provided with
the kit.
* The EPA standard states that it is necessary to perform certification testing with any ventilation that is likely to
alter the units’ performance. For this reason, SBI has tested the effects of the forced air kit on the emissions of fine
particles. Due to the design of the appliance and more specifically to the temperature sensor that is installed to
control stops and starts, the forced ait kit does not affect the emission results. In fact, this option promotes the
recovery of excess heat to later redistribute it to other rooms. During testing, it was noted that the convection
blowers underneath the firebox had more of an effect on the fine particles emission due to the air being directed
onto the firebox thus cooling the unit. However, this appliance has already been tested for emission with one or
more convection blowers. The environmental requirements are then met efficiently.
