Clearances Requirements - Bioethanol Built-in Fireplace Inserts

- · Updated:
Before installing your EcoSmart Fire built-in fireplace insert, you’ll need to confirm the right clearances, ventilation and minimum room sizes for your specific model. This guide walks architects, builders and installers through the requirements for Flex, Heritage and Frame fireplaces, covering both indoor and outdoor placement so your installation is safe, compliant and ready to enjoy.
Selecting appliance location
The appliance is zero clearance and has the necessary clearances to combustible frame components already built-in. They are engineered specifically to accept compatible EcoSmart Fire Burners.
When selecting a location for the appliance it is important to consider the required minimum room sizes and clearances to walls and combustible materials (see Clearances images below and Minimum Room Size table).
Note: Appliances are made from zinc sealed steel which is powder coated with super hi-temp black paint which prevents rusting. The burners are made of 304 stainless steel. To ensure the burner(s) continue looking great and to avoid rust or corrosion it is important any contamination or debris are cleaned or removed from the burner immediately.
If installed outdoors, the appliance must be located under a protective overhang to avoid it from filling with water and being permanently damaged. The warranty is void if the product is damaged as a result of installation in an exposed location.
When not in use, keep the burner lid closed to safeguard the burner from debris falling into the burner chamber and causing contamination.
WARNING: Risk of Fire or Burns! Provide adequate clearance around air openings and for service access. Observe the clearances to combustibles recommended in this manual and the burner manual. Ensure that your fire is positioned away from flammable materials and other sources of ignition at all times. Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies. Pay very close attention to positioning the fire away from items that may move as a result of wind and drafts. For example trees/branches/curtains/paper and the like. Keep children at a safe distance at all times and never leave them unsupervised when the appliance is on or hot.

Indoor Clearances

Outdoor Clearances (Need overhang or “roof extension” above the fireplace to ensure rain will not enter the firebox. Check with local building codes regarding requirements for overhangs / roof extensions.)
Ventilation
EcoSmart Fires do not require any form of permanent fixture or fitting, such as a flue for ventilation, a permanent connection or any kind of fixed utility for fuel supply.
Do not cover any existing ventilation systems or structures that are built or installed within the chosen installation area.
To ensure adequate ventilation, make sure to follow the guidelines in the table shown.
Underwriters Laboratories (UL) calculates adequate air exchange as follows:
In a house of typical construction, that is, one that is not of unusually tight construction due to heavy insulation and tight seals against air infiltration, an adequate supply of air for combustion and ventilation is provided through infiltration. However, if the Burner is used in a small room where less than 5.7m3[200ft3] of air space is provided for each 1000 BTU per hour of appliance rating (considering the maximum Burner setting), the door(s) to adjacent room(s) should be kept open or a window to the outside should be opened at least 25.4mm[1in] to guard against potential build up of indoor air pollution. Do not install or operate in a bathroom or any other small room.
