Product Features
Compact Zone Heating Performance
Designed for spaces from 250 to 1,200 ft², the Spark II N delivers up to 75,000 BTU/h of maximum heat output in a compact 18 1/2" W x 29 3/4" D x 28 3/4" H footprint, subject to installation and operating conditions.
EPA 2020 Certified Clean Combustion
This non-catalytic stove is EPA 2020 approved with an average particulate emission rate of 1.7 g/h and includes a stainless steel secondary-air system.
NexBurn Technology with Combustion Grid and Tertiary Zone
NexBurn technology supports more complete combustion, working with a combustion grid that promotes quick ignition and optimizes burn efficiency. A newly added tertiary combustion zone further enhances heating performance.
Deep Firebox with Extended Ash Capacity
The deeper firebox allows a greater accumulation of ashes, so the firebox can be emptied less frequently.
Glass Airwash System
An integrated airwash system helps keep the 10 1/4" x 8 1/2" ceramic glass clearer for a better view of the flames through the single cast iron framed door.
Simple Assembly and Installation Versatility
Packaged in a rigid box for ease of transport, the Spark II N is simple to assemble and is certified for alcove installation and for mobile homes when equipped with a fresh air intake, installed according to the owner’s manual. An optional blower of up to 100 CFM can be added.
Durable Steel Construction
The body is built from 3/16" steel with a 1/4" steel top reinforced with a stainless steel heat shield, over a refractory brick-lined firebox with a high quality vermiculite baffle, backed by a limited lifetime warranty.

Manufacturer Notes
- Recommended heating area and maximum burn time may vary with location in the home, chimney draft, heat loss factors, climate, fuel type, and other variables.
- Maximum heat output (dry cordwood) is based on a loading density of 15–20 lb/ft³; other performance figures are based on the standard test fuel load of 7–12 lb/ft³ at 19–25% moisture content.
- Efficiency values are measured per the CSA B415.1-10 stack loss method; optimum heat transfer efficiency reflects the low burn rate (HHV).
- Any installation must be done according to the data and drawings detailed in the owner’s manual.
