DESCRIPTION
The Tjernlund Power Venter models HS3, HS4 and HS5 are designed to Side Wall or Vertically vent Natural and LP Gas appliances.
After each burner cycle the Venter will continue to operate in post-purge mode to purge the heater and vent of residual flue gases. A
factory post-purge time is set at 2 minutes and is adjustable up 16 minutes, see “Pre / Post-purge Settings” on page 5. The Venter
features a safety system consisting of the integral UC1 Universal Control and a Fan Proving Switch. These devices monitor the
Venter’s performance and will interrupt the main burner if a venting malfunction is detected.

VENTER SIZING
The installer must verify that the Power Venter is sized properly using the selection table on page 2. The installer may reduce the
vent pipe diameter to the size shown in the selection table immediately after the draft hood, draft diverter or barometric draft control.
The vent pipe length shown includes all vent pipe before and after the Power Venter. To calculate the equivalent vent pipe length,
add the straight vent pipe plus 10 feet for every 90 degree elbow and 5 feet for every 45 degree elbow.
If venting multiple appliances with one Power Venter, the total combined BTU/hr. input of all appliances must be added together to
size the Power Venter.
IMPORTANT: Elbows placed directly after discharge on Power Venter may cause erratic operation of Fan Prover. If elbows are
necessary on discharge, allow for a straight section of pipe 3 times the vent diameter being used before installing an elbow.

INSTALLATION RESTRICTIONS
1. The Power Venter may only be installed on Natural Gas or LP Gas appliances.
2. The Power Venter may not be installed on incinerators, incinerating toilets, condensing-type appliances or solid-fuel burning
appliances.
3. The Power Venter shall not be installed on an appliance with an automatic valve having a manual opener unless the manual
opener has been rendered inoperative or the automatic valve has been replaced with a valve not equipped with a manual opener.
4. The Power Venter may only be installed on an appliance equipped with a draft hood, draft diverter or barometric draft control.
5. The Power Venter shall not be installed where the flue gas temperature exceeds 600oF. at the Power Venter inlet. Flue gas
temperature verification:
A) Consult appliance manufacturer for flue gas temperature after dilution by the draft hood, draft diverter or barometric draft control.
B) Measure flue gas temperature at the Power Venter inlet after installation. Temperature should be measured after appliance and
Power Venter have operated for at least 15 minutes, allowing the flue gas temperature to stabilize.
6. The Power Venter must be mounted so that the shaft of the motor remains horizontal to prevent motor bearing wear.
7. Fan Proving Switch must be mounted with diaphragm in a vertical position. Do not mount the Fan Proving Switch on a heat source
that exceeds 140oF. Examples of improper mounting surfaces include vent pipe, venter, top of heater casing or any place where
radiant or convective heat would exceed 140oF.
8. Ambient temperature surrounding Power Venter must not exceed 104o F.
9. The UC1 is intended for indoor installation only. Do not mount the UC1 junction box on a heat source that exceeds 140oF.
Examples of improper mounting surfaces include vent pipe, top of heater casing or any place where radiant or convective heat
would cause the junction box temperature to exceed 140oF.

444444444444444 CAUTIONS
INSTALLER CAUTIONS
The Power Venter must be installed by a qualified installer in accordance with these instructions and all local codes or in their
absence in accordance with the latest edition of The National Fuel Gas Code (NFPA #54), The latest edition of the National Electrical
Code (NFPA#70) and the Occupational Safety and Health Act (OSHA) when applicable. Improper installation can create a hazardous
condition such as an explosion, fire, electrical shock or carbon monoxide poisoning resulting in property damage, personal injury or
death.
Failure to install, maintain and/or operate the Power Venter in accordance with manufacturer's instructions may result in conditions
which can produce bodily injury and property damage.
Disconnect the power supply from UC1 and heating equipment when making wiring connections or when working around the fan
wheel and motor. Failure to do so can result in electrical shock, personal injury, death or property damage.
1. The Fan Prover must be wired with the appliance so as to prevent the main burner(s) from firing if the Power Venter malfunctions
or the flue is blocked. It is not safe to use the Power Venter as is on millivolt appliances, such as water heaters which employ a
combination gas valve/temperature controller, since the Fan Prover can not be wired as described in this manual. Millivolt appliances require additional interlock controls such as our WHKE kit. See millivolt wiring diagram in this manual for more details.
2. Plan the vent system so that the code required clearances are maintained from plumbing and wiring.
3. To prevent personal injury and equipment damage, disconnect power supply when working on Power Venter.
4. Make certain the power supply is adequate for Power Venter motor requirements. Do not add the Power Venter to a circuit where
the total load is unknown.
5. The installer must verify that the appliance on which the Power Venter will be installed is in a safe operating condition. Consult
appliance manufacturer’s Instructions for details.
6. Plan the vent system layout so that the Power Venter is as close to the point of termination as possible. Vent pipe between the
Power Venter and Vent Hood is acceptable. However, all vent pipe connections after the Power Venter discharge will be under positive pressure during operation and must be sealed with high-temperature caulk or aluminum vent pipe tape to prevent flue gas leakage into the structure.
