Extended Base
The Extended Base upgrade for the S500 gives it an extra-large ash pan that is 3x bigger than the standard ash pan, which greatly extends the time period between emptying. It also makes the ash pan accessible to front-end loaders making dumping the ash hands-free.
Domestic Coil
This Domestic Coil features a 100° F rise at 5 gallons per minute, 50° water inlet temperature and 65 PSI water pressure. It is threaded into a 4 IN NPT threaded fitting provided on the boiler for this purpose.
Warnock Hersey Certification
WH certification is available on all Coal Gun boilers for an additional charge. This certification assures that the boiler complies to UL 2523 Standards. Some insurance companies may require this certification and it is the responsibility of the homeowner to determine the need for a WH certification on any boiler purchased.
Auger Loading
The Coal Gun can be enhanced with an auger add-on that eliminates the need to manually fill the hopper. This is especially important on the large models (S500, S1000), as a higher demand for heat requires more regular filling. Auger add-ons have both automatic and manual settings for maintaining coal reserves.
4″ or 6″ Diameter
Your choice of diameter will depend on load size and cleanliness of coal. If your coal typically has debris, like wood chunks, a 6″ auger would be recommended. Auger length can be customized per requirements.
Auger Inlet Guard
An auger inlet guard provides added safety. The guard’s sturdy mesh screen prevents unwanted objects from contacting the auger screw.
Low Water Cutoff
A Low Water Cutoff senses the water level in the boiler’s vessel and will shut the unit down if the water level drops to an unsafe level.
