WARNINGS
WARNING
Improper installation, adjustment, alteration, service
or maintenance can cause property damage, injury
or death. Read the installation, operating and
maintenance instructions thoroughly before
installing or servicing this equipment.
FOR YOUR SAFETY
Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any other
appliance. If you smell gas:
1. Open windows
2. Don’t touch electrical switches
3. Extinguish any open flame
4. Immediately call your gas supplier
OWNER
Retain this Manual & ensure available for service.
Improper installation, adjustment, alteration, service
or maintenance can cause injury, death or property
damage.
Read the installation, operation and service
instructions thoroughly before installing or servicing
this equipment.
INSTALLER
Provide Manual to Owner upon completion of
installation!
Read and thoroughly understand these Instructions
before attempting any installation
CAUTION: FIRE OR EXPLOSION HAZARD
Maintain clearance to combustible constructions as
further specified in this manual. Failure to do so
could result in a serious fire hazard. Heaters should
not be located in hazardous atmospheres containing
flammable vapors or combustible dusts. Signs
should be provided in storage areas specifying
maximum safe stacking height.
CAUTION: MECHANCIAL HAZARD
This equipment expands and contracts with each
operating cycle. The gas connection, suspension
hardware and the installation itself must safely allow
this movement. Failure to do so could result in
serious fire or explosion hazard.
CAUTION: FIRE OR EXPLOSION HAZARD
This heater is equipped with an automatic ignition
device. Do not attempt to light the burner by hand.
Failure to comply could result in a serious fire and
personal injury hazard.
CAUTION: MECHANCIAL HAZARD
Do not use high pressure (above 1/2 psi) to test the
gas supply system with the burners connected,
doing so could result in damage to the burner and
its control components requiring replacement.
Do not install equipment in atmospheres containing
halogenated hydrocarbons or other corrosive
chemicals, doing so may lead to premature
equipment failure and invalidation of the warranty.
Additionally, it is recommended that the equipment
be installed with a slope downward and away from
the burner of ¼" (6mm) in 10' (3m) to allow start-up
condensate drainage.
CAUTION: SERVICE LIFE RISK
Due to continuous product innovations, we reserve the right to change product specifications without due notice.

IMPORTANT
These instructions, the layout drawing, local codes and ordinances, and applicable standards such
as apply to gas piping and electrical wiring comprise the basic information needed to complete the
installation, and must be thoroughly understood along with general building codes before proceeding.
Only personnel who have been trained and understand all applicable codes should undertake the
installation. Representatives that are Factory Certied in the service and application of this equipment
and can be called on for helpful suggestions about installation.
Installation Codes
Installations must comply with local building codes, or in their absence, the latest edition of the national
regulations and procedures as listed below.
General Installation and Gas Codes

INTRODUCTION
Advanced Radiant Systems’ unitary agship is the Modulating Unitary Range (VA). The VA Range boasts the
highest turndown ratio in the industry on a unitary heater. Unlike other manufacturers’ units, the VA Range
modulates both fuel and air simultaneously for a true modulation benet. By meeting building envelop heating
demands on an ongoing basis, energy consumption is minimized. Occupant comfort is also enhanced by
offering a more consistent temperature output than found with single and dual stage heaters. These units are
exceptionally suited for those areas in a facility with inconsistent heating demands.

In addition to this it is very important to observe the minimum clearance to combustibles at all times to
avoid any possibility of property damage or personal injury.

appropriate markings adjacent to the thermostat or in a conspicuous location.
Table 2 lists the minimum clearance to combustible materials for various installation congurations. Note
that standard clearances also apply to installation above T-bar ceilings and above decorative grills. Additional
clearance may be required for glass, painted surfaces and other materials which maybe damaged by radiant or
convective heat.
Combustible materials are considered to be wood, compressed paper, plant bers, plastics, Plexiglas or other
materials capable of being ignited and burned. Such materials shall be considered combustible even though
ameproofed, re-retardant treated or plastered.
Elbows and U-bends are non-heat treated aluminized material and are typically installed without reectors.
Reector miter kits are available for U-bends and elbows. Clearance around non-reector ttings is 18”, unless a
reector kit is used, refer to table 2.
Adequate clearance to sprinkler heads must be maintained (NFPA 13: Standard for the Installation of Sprinkler
Systems).
The stated clearance to combustibles represents a surface temperature of 90°F (32°C) above room temperature.
Building materials with low heat tolerance (i.e. plastics, vinyl siding, canvas, tri-ply, etc.) may be subject to
degradation at lower temperatures.
It is the installer’s responsibility to ensure that adjacent materials are protected from degradation.
Table 2: Minimum Clearance to Combustibles (pp. 6-8)
Note 1: Bottom Shields are approved for all burner sizes. The “below” clearance (dimension C in
Table 2)may be reduced by 25% when an approved Bottom Shield is used.

INSTALLATION
Installation Sequence
Generally, there is no unique sequence for installation of the burner or heat exchanger. A review of the job site will
usually indicate a logical installation order. However, time and expense can be saved if installation is begun at the
most critical dimension, watching for interference from overhead doors, cranes, auto lifts etc. Figure 5 provides a
general overview of the components utilized in the installation, as well as their general relationship

••Note: For all coupling joints, ensure that the tube joint is in the center of the coupling length, and that the
overlap joint of the coupling is above the centerline of the tube. Also ensure that the weld seam on ALL
tubes is facing down.
••Note: In order to obtain smoothly sealed coupling liners, tighten each of the coupling bands
progressively and alternately. Tightening one band completely before the other may result in an
undesirable wrinkle in the liner (refer to Figure 11).
DO NOT over torque the coupling. (Torque coupling to 15-25 lbf-ft).

••Note: Bafes are always placed at the end of the last heat exchanger tube length, with the exception to
the special congurations (115,000 BTU/H with a 40’ tube length, and 200,000 BTU/H with 50’ and 60’
tube length) refer to Figure 3 for more details.
••Note: Bafes are either one or two sections (each section is 6' in length). Multiple sections are simply
coupled together. Where stainless and aluminized sections are supplied, always place the stainless steel
section closest to the burner. The easiest installation method is to pull the bafe through the tube using a
long wire.
