Retro Fit Upgrade Kit

We are supplying all units with an upgrade kit to reduce the unlikely chance of failure or fire.  This kit is being furnished free of charge.  If you don't have your retro fit kits, please call or email us and we will ship them out immediately.  The kits take less than 5 minutes to install, and require no special tools.  Their purpose is to prevent the supply hose from coming in contact with the back of the heater.  The kit does not in any way change how the unit functions, nor it's operation.

Instructions on how to install the retro fit kit are included with the kit and all replacement heater...or you can view the instructions by clicking the link below:
