Field Controls PVG-100 power venter unit in galvanized steel housing

Field Controls

Field Controls PVG-100 Power Venter 115V 100k BTU HVAC control

SKU CH-PRDZ-F1X3N

Vents gas furnaces, boilers and water heaters up to 100 000 BtuH with a 115 V motor

  • Vents gas appliances up to 100,000 BTUH input
  • Runs on standard 115V AC household power
  • Fits 3 in to 4 in vent pipe diameters
  • Replaces Tjernlund HS1, HST-1 and HSUL-1 models
  • Suitable for LP and natural gas furnaces, boilers and water heaters

Application Scope

The Field Controls PVG-100 Power Venter serves gas-fired furnaces, boilers and water heaters rated up to 100,000 BtuH. It handles both LP and natural gas fuels at a nameplate voltage of 115V AC. Installers use it where a conventional chimney draft is insufficient or unavailable.

Replacement Compatibility

The unit replaces Tjernlund models HS1, HST-1 and HSUL-1, allowing a direct swap on existing 4 in vent piping. Inlet and outlet diameters both measure 4 in, while the acceptable vent pipe range spans 3 in to 4 in. No additional adapters are required for those specific replacements.

Construction and Connections

Galvanised steel housing resists corrosion in typical mechanical-room environments. The 115V AC supply connects to standard wiring practices for heating appliances. Fixed 4 in inlet and outlet collars simplify alignment with rigid or flexible vent pipe within the stated diameter limits.

Questions about this item

Will the 4-inch galvanized steel vent pipe need periodic cleaning or replacement?

The galvanized steel construction resists corrosion, so the 4-inch vent pipe does not require scheduled replacement; inspect annually and clear any debris that may restrict airflow.

What limits continuous operation when the venter runs at the 100,000 BtuH maximum?

The 115V AC motor is rated for the full 100,000 BtuH gas input, so the thermal protection in the motor winding is the first limit reached under sustained high-fire conditions.

How much noise and heat does the 115V motor produce during all-day heating cycles?

The direct-drive motor operates at a low sound level typical for residential power venters, and motor heat is discharged into the vent stream rather than the mechanical room.
