All CATCO catalytic heaters include an instruction manual with specific steps for installation. CATCO products are intended for industrial use only and should only be installed and operated by professionals with appropriate training in gas, electrical, and general personnel safety. If at any time you need guidance on how to safely install or operate CATCO products, please contact your CATCO distributor or our factory at 972-563-8065.
Installation is limited to connecting to a suitable gas supply. Heaters may be started using either DC or AC power, making them ideal heating sources for remote locations where electrical power is limited or not available. For natural gas fired heaters, fuel gas is usually readily available on site. It’s critical the unit be installed so the face of the heater is protected from rain and snow.
Installation must conform with local building codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code, CSA B149.1. When installing a Catco heater in a hazardous location such as a Class I, Division 1 or Division 2, Group D area, ensure that all associated electrical equipment is appropriately rated for the area where it will be installed.
Before the catalytic reaction that produces heat can begin, the catalyst bed must be preheated to approximately 250° F (121° C). This is accomplished by energizing internal electric heating elements using the voltage specified on the heater’s label. Electrical power is only required during the start-up phase of operation (typically no more than 30 minutes).
1. Verify the unit has been installed in accordance with your product’s instruction manual and all applicable codes.
2. Make sure the electrical supply matches the voltage specified by the product label and turn on the electrical supply.
3. Wait 15 minutes to allow the catalyst bed to come up to temperature (this may take longer in extremely cold weather).
4. Press and release the button on the shutoff valve to start the flow of fuel gas to the heater. This will start the catalytic reaction.
5. Continue electrical power until the catalytic reaction is fully established. This will be indicated by a rapid rise in face temperature and the emission of hot exhaust gases. Under normal conditions, this phase will take 5-10 minutes.
6. Once the reaction is established, turn off the electrical power. The heater is now in normal operation.
The catalyst material is not consumed or destroyed by the catalytic reaction, and the reaction will continue as long as the heater is provided with a clean fuel supply and adequate combustion air.
1. Ensure the electrical power is turned off.
2. Turn off the fuel supply.
3. Removing the fuel supply will cause the catalytic reaction to stop. Don’t handle the unit until it’s sufficiently cooled.
Catco catalytic heaters contain no moving parts and maintenance is minimal. Sheet metal surfaces may be cleaned to prevent rust or corrosion, but take care to protect the face of the heater from contact with water, cleaners, or other foreign substances.
If an area is being cleaned with high pressure water spray or air pressure, shield the face of the heater, as the catalyst can be damaged by water or rough contact.
When not in use, heaters should be stored in a clean, dry area or covered to prevent damage from the environment, insects, and rodents.
If at any time you have questions about the servicing, repairing or maintaining your CATCO heater, please contact your CATCO distributor or call our factory.
