APPENDIX 2 - FORCED AIR DISTRIBUTION KIT* (VA4460)
It is possible to connect a forced air distribution kit on either sides of the HORIZON.
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.
*
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 our 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 our 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. In conclusion, we have satisfied the environmental requirements efficiently
