A combustion chamber subassembly for use with a pressure washer, the combustion chamber subassembly comprising:
- a top bell member defining an interior combustion chamber and an exterior, the top bell member including a top diffuser wall, a first side wall extending from the top diffuser wall toward the interior combustion chamber of the top bell member, a second side wall extending from the first side wall toward the exterior of the top bell member;
- and
- a gasket that is attached to the top bell member, contacting the first side wall and the second sidewall.
A blower and heat exchanger assembly comprising;
- a blower subassembly;
- a support frame;
- and
- a heat exchanger subassembly including
- an ignition subassembly;
- a combustion chamber subassembly;
- an inner shell;
- an inner coil of heat exchange tubing;
- and
- an outer coil of heat exchange tubing;
- wherein the heat exchanger subassembly defines a first flow passage between the inner coil of heat exchange tubing and the outer coil of heat exchange tubing, a second flow passage between the outer coil of heat exchange tubing and the inner shell, and a sealed passage between the combustion chamber subassembly and the inner coil of heat exchange tubing.
A method of assembling a heat exchanger subassembly comprising:
- attaching a top bell member having angled side walls to a cover;
- attaching a bottom member to the top bell member;
- and
- attaching a gasket to the angled side walls of the top bell member, forming a combustion chamber subassembly.
