31
HLV Series 3.0 Installation • Venting Requirements
Flue Venting
WARNING
!
Insufficient ventilation and/or improperly sealed vents may release gas into the building
which could result in health problems, carbon monoxide poisoning or death.
Improper venting may result in fire, explosion, injury or death.
Seal vent pipes with high temperature sealant and three (3) #8 sheet metal screws.
Vent enclosed spaces and buildings according to the guidelines in this manual and
applicable national, state, provincial and local codes.
Prior to installing vent material, the following guidelines and all applicable codes must be observed to
ensure proper system performance and safety. Local codes may vary. In the absence of local codes,
refer to and comply with the National Fuel Gas Code ANSI Z223.1 (NFPA 54) latest edition. In Canada,
refer to and comply with CAN/CGA B149.1 and B149.2 Installation Codes for Gas Burning Appliances, or
the National Standards of Canada.
Flue Venting General Requirements:
1 The HLV System is designed to operate with a 4 in. diameter exhaust vent.
2 Single-wall 26 gauge (min.) flue vent must be used. Use only corrosion resistant materials for the
discharge line from the pump to the point of discharge.
3 The use of an approved wall or roof thimble and double-wall Type B-vent is required for the
portion of vent pipe that runs through combustible material in the building wall or roof.
4 Seal all flue vents with high temperature sealant and three (3) #8 sheet metal screws to prevent
leakage of flue gases.
5 Maximum vent length is 25 ft.; minimum of 2 ft. If needs are otherwise, consult factory for approval.
6 Do not use more than two 90° elbows in the exhaust vent.
7 Protect vent cap from potential blockages, such as snow.
8 Vent must terminate a minimum of 4 ft. (1.2 m) below, 4 ft. (1.2 m) horizontally from, and 1 ft.
(30 cm) above any window or door that may be opened or gravity air inlet into the building.
9 Vent must terminate a minimum of 3 ft. (.9 m) above any forced air inlet that is located within
10 ft. (3.1 m).
The bottom of the vent terminal must be located a minimum of 12 in. (30 cm) above grade level
and must extend beyond any combustible overhang. Vents adjacent to public walkways must
terminate a minimum of 7 ft. (2.1 m) above grade level.
Vent must be a minimum of 36 in. below or extend beyond any combustible overhang.
Protect the building from potential damage or discoloration resulting from flue gases by
maintaining a minimum distance of 6 inches from the sidewall of the building. On condensing
systems, extend the vent a minimum of 2 ft. beyond the building exterior to protect from
condensate drippage.
A condensate trap is required on condensing systems if a vertical rise exists in the discharge
line (Figure 3.19). For ease of condensate disposal, horizontal venting is recommended. Unless
local codes dictate otherwise, the condensate trap can be eliminated if a horizontal discharge is
pitched downward 1 in./Ft. (Figure 3.18). Adhere to local codes for proper condensate disposal.
Consult the NFPA ANSI Z223.1 Gas Vent Termination criteria if roof pitch exceeds 9:12.
The vent terminal must extend a minimum of 2 ft. (.6 m) above the roof.

HLV Series 3.0 Installation • Combustion Air Requirements
Combustion Air Requirements
This heater has a factory preset air orifice to provide adequate combustion air intake to the unit.
Non-contaminated outside air for combustion must be ducted to the heater if any of the following apply:
• Chemicals such as chlorinated or fluorinated hydrocarbons are present in the space where the heater
is installed (typical sources are refrigerants, solvents, adhesives, degreasers, paints, paint removers,
lubricants, pesticides, etc.).
• Negative building pressure.
Indoor air supply: If using combustion air intake from indoors, the required volume of the space must be
a minimum of 50 ft3 per 1000 Btu/hr (4.8 m3/kW) unless the building is of unusually tight construction. If
the building is of unusually tight construction with air infiltration rates of less than 0.40 air changes per
hour, outside combustion air is typically needed unless the sheer size of the building allows otherwise.
Contact the factory for further determination of air infiltration rates.
Outside air supply: Outside combustion air may be supplied via an accessory air duct attached directly
over the air orifice. A wall inlet cap (P/N: WIV) must be used with horizontal air intake ducts. It is
recommended that the air intake pipe is connected to the heater with a 4 in. diameter flexible air inlet boot
(P/N: AIRH) to allow flexibility for expansion (Figure 3.20). Sidewall (horizontal) air intake is preferred.
Refer to Chart 3.3 for limitations on the length and size of air intake ducts.
• A maximum of two elbows is allowed in the vent.
• Keep air intake opening a minimum of 4 ft. from any exhaust vent openings. Always place vent stacks
higher than air intake openings.
• An air intake cap (P/N: WIV) must be installed to prevent blockages. Locate intake cap in an area
where dirt, steam, snow, etc. Will not contaminate or clog the intake screen.
• Insulated duct or PVC pipe should be used in humid applications to prevent condensation on the outer
surface of the intake pipe.

HLV Series 3.0 Installation • Gas Supply
Gas Supply
WARNING
!
Improperly connected gas lines may result in fire, explosion,
poisonous fumes, toxic gases, asphyxiation or death. Connect
gas lines in accordance to national, state, provincial and local
codes.
The installation must conform with local building codes or, in the absence of such codes, the National Fuel
Code (NFPA 54) and in conjunction with ANSI Z21.24/CSA 6.10 “Connectors for Gas Appliances”.
Important! Before connecting the gas supply to the burner control box:
• Verify that the heater’s gas type (as listed on the rating plate) matches that of your application.
NOTE: Unless otherwise noted on the rating plate, this infrared heater is designed and orificed to
operate on standard BTU gas. Contact the factory if utilizing non-standard BTU gas.
• Check that the gas piping and service has the capacity to handle the total gas consumption of all
heaters being installed, as well as any other gas appliances being connected to the supply line.
• Check that the main gas supply line is of proper diameter to supply the required fuel pressures.
• If utilizing used pipe, verify that its condition is clean and comparable to a new pipe. Test all gas
supply lines in accordance with local codes.
• Test and confirm that inlet pressures are correct. Refer to the heater rating plate for gas type and
the required minimum and maximum pressures (Chart 3.5). The gas supply pipe must be of
sufficient size to provide the required capacity and inlet pressure to the heater (if necessary,
consult the local gas company). Do not exceed the maximum allowed pressures for the heater,
the space or the gas piping system.

Chart 3.5 Manifold Pressure
NOTE: Check manifold pressure at the tap on the gas valve. Small variations in manifold pressure
(actual vs. published) may exist due to changing atmospheric conditions. Readings will be above
atmospheric pressure.

IMPORTANT! The heating system will expand and contract during operation. Allowances for
expansion must be made between the connection to the heater and the gas supply. Excessive
bending, kinks, twists or vibration must be avoided. A flexible gas connection of approved type is
required. A type 1 rubber gas connectors installed in one plane, and without sharp bends, kinks or
twists.
3.0 Installation • Gas Supply
WARNING
!
An approved connector, suitable for the environment of equipment usage, is required.
Visible or excessive swaying, flexing and vibration of the gas connections must be
avoided to prevent failure. In no case shall the gas or electrical supply support the
weight of the heater.
The gas pipe and connection must be supported independently. Do not install gas supply line in a manner
that bears the weight of the heater. Connect the main gas supply line with an approved flexible connector
(Figures 3.26-3.27) or, if national or local codes require rigid piping, a swing joint. Heater shall not be
connected to the building piping system with rigid pipe or semi-rigid metallic tubing, including copper.
When using such material, an intermediate connection device that allows for heater expansion must be
used.
The gas outlet must be in the same room as the appliance and accessible. It may not be concealed within
or run through any wall, floor or partition. When installing the heater in a corrosive environment (or near
corrosive substances), use a gas connector suitable for the environment. Do not use the gas piping
system to electrically ground the heater.
1 Install a sediment trap / drip leg if condensation may occur at any point of the gas supply line or as
required. This decreases the possibility of loose scale or dirt in the supply line entering the heater’s
control system and causing a malfunction. NOTE: High pressure gas above 14 Inches W.C.. (water
column pressure) requires a high pressure regulator and ball valve.
2 Form the Type 1 rubber gas hose into a smooth U-shape allowing a maximum of 14 in. between the
flexible connector’s end nuts (Figures 3.26-3.27).
3 Attach the ball valve to the gas supply pipe. Apply pipe compound to NPT adapter threads to seal the
joint. Use only a pipe compound resistant to LP.
NOTE: Provide a 1/8 in. NPT plugged tapping accessible for test gauge connection immediately
upstream of gas connection to the heater (provided on ball valve).
4 Attach the flexible connector to the adapter and burner control box inlet. Seal the joints.
Note: Excessive torque on the manifold may misalign the orifice. Always use two wrenches to tighten
mating pipe connections.
5 Final assembly must be tested for gas leaks according to NFPA 54 and all local codes and/or Standards.
WARNING
!
Testing for gas leaks with an open flame or other sources of ignition may lead to a fire or
explosion and cause serious injury or death. Test in accordance with relevant codes of
practice.
