The new document holder is now offered with all 2020 and newer heater models for the Blaze series and the Fire 155. The canister can be purchased separately and mounted to older units as you see fit. The document holder allows for all service manuals, exploded views, and maintenance parts to travel with the heater so that you are never stuck in the cold with a heater that will not fire.
Be sure to print off the service manuals located in each heater page under ‘Documents’ and also purchase a repair kit. Standard tools to repair any heater would be a #2 screw driver, a set of metric allen wrenches, and two channel lock pliers.
