AC-BC Valve FEATURES
- 3/8″ NPT shut-off ball valve body; female NPT inlet and outlets made from forged brass to increase strength and nickel-plated for added corrosion resistance
- Hard chrome-plated ball has Teflon® seats and an anti-corrosion Dacromet treated handle
- Supplied standard for all CSA-approved Cata-Dyne™ heaters.
- CSA approved; UL listed
1/ Thermon Cata-Dyne Valve
• This valve is designed with a bulb and capillary assembly that automatically regulates fuel flow to a
Cata‑Dyne™ heater from 100% when heat is required to approximately 30% when the thermostat is
satisfied
• This unit is used to control building temperature for spot and space
heating applications
• The sensing bulb is filled with a temperature sensitive liquid. Changes in the temperature at the bulb
expand and contract the liquid on temperature rise and fall causing the internal mechanism to modulate
the flow of fuel
• Temperature control range of 0°C to 44°C (32°F to 110°F)
• Maximum inlet pressure of 1/2 psi
• Each unit has a connection size of 3/8″ NPT female and a capillary length of 5 ft (1.5 m)
• No electrical power is required to operate this unit
• Controls are factory set to specific Btu and fuel ratings for specific heater types and sizes. Contact
factory for the appropriate thermostat control valve.

2/ Thermon Cata-Dyne Valve
Manual Shut-Off Ball Valve,
The ball valve is installed upstream of all auxiliary heater controls to manually shutoff
the fuel supply to the Cata‑Dyne™ heater, see installation instructions for correct
configuration for each fuel type
• A 3/8″ NPT shut-off ball valve, with female NPT inlet and outlets in forged brass which
increases the strength of the body
• Supplied with all manually controlled Cata‑Dyne™ heaters
• The hard chrome-plated ball has Teflon seats and an anti-corrosion Dacromet treated
handle
• Certifications
–– CSA approved and UL listed
3/Thermon Cata-Dyne Valve
Thermocouples:
The Type K Thermocouple is a probe made from two dissimilar metals that monitors
the temperature of both the electrical start-up element and the underside of the
catalyst pad inside the Cata‑Dyne™ heater
• Certifications
–– Thermocouples are CSA approved

Gas Pressure Regulators:
• All regulators are designed to ensure there is a precise control of gas or propane flow
• The regulators are part of the piping system connecting to the Cata‑Dyne™ units, see installation and
operating instructions for precise configuration
• The following three types of regulators are available: Appliance Regulators, Service or Low Pressure
Regulators and High Pressure Regulators
Standard Appliance Regulator (AC-R-ES404-7)
• The appliance regulator is used for controlling the manifold pressure on all natural gas Cata‑Dyne™
heaters and is supplied with all CSA certified models
• It is a spring type, nonadjustable appliance regulator with a maximum inlet pressure ½ psig
• Available pressure outlet settings are: 3.5″, 4.5″ and 7.0″ w.c.
• Maximum flow capacity: 65,000 Btu/hr
• Certifications
–– Appliance regulators are CSA approved
Standard Service or Low Pressure Regulator (AC-R-2511)
• Used as an appliance regulator for all model sizes of Cata‑Dyne™ heaters operating on LPG, and serves as
a natural gas low pressure line regulator when used in conjunction with the ES-404 gas appliance regulator
• Self-operated, spring loaded device that is field adjustable
• It has a maximum inlet pressure of 250 psig and is factory set at 11″ w.c. or 4.5″ w.c. outlet pressure, with a
connection size of 1/4″ NPT inlet by 3/8″ NPT outlet
• For gas applications with inlet gas less than 25 PSI use service regulator AC-R-HSR or AC-R-325
• Ambient temperature range: -40°C to 55°C (-40°F to 130°F) or -29°C to 70°C (-20°F to 160°F)
(Fisher regulator only)
• 1/8″ NPT screwed vent connection is provided
• Certifications
–– Low pressure regulators are CSA approved
