B . Mechanical contractor shall provide a complete control system including any step-up/down transformer
for 24 AC control, relays, relay boards, relay bases, printed circuit boards, or any other necessary
devices, including enclosures for equipment shall be furnished by the mechanical contractor. When
shown on Drawings, mechanical contractor shall also furnish and install the following Novar Controls
equipment, according to Novar Controls printed installation and hardware mounting procedure. Refer
to Drawings for location of Electronic Thermostat Module and Baseplate. No deviations from these
instructions and mc. '`ng procedures shall be accepted. All Novar Controls equipment shall be
installed under the s_.Nervision of the Energy Management contrartor.
1. Electronic Thermostat Module: ETM -2020
2. ETM Baseplate: ETM -BPL
C. Contractor shall follow urn Manufacturer's printed installation and start-up instructions, and verify
proper operation.
D. Contractor shall schedule start-up allowing Owner's representative to be present unless Owner
directs otherwise. If all start-up procedures can not be properly done due to seasonal weather
conditions, remaining tests shall be performed at an appropriate time. Payment may be withheld
until work is complete. Durirg start-up Contractor shall operate each unit with Energy Management
System for a sufficient period of time demonstrating to the Owner's satisfaction that the unit is
operating properly.
E. During first -year warranty, Contractor may be required to demonstrate that the systems are operating

2.07 UNIT HEATERS - GAS FIRED
A. Unit Heaters: Heavy -duty type which are design certified by A.G.A., comply with current OSHA
requirements, accepted by FIA/FM and UL listed. Heaters shall have direct ignition spark of the
pilot ignitor through a solid-state, direct-spark ignition system. Loss of gas or power shall cause
100% shut -off of main burner and pilot. Heater shall be equipped with controls for 24 VAC
thermostatic operation as manufactured by one of the following:
1. Dravo - Hastings.
2. Lennox.
3. Modine.
4. Reznor.
5. Sterling.

enclosures for equipment shall be furnished by the mechanical contractor. Refer to drawings for
location(s) and type(s) of thermostats, timers, etr.
E. Where attitude Is above 2,000 ft, gas unit heaters are rat derated, but may require larger orifices to
ensure full gas input for proper radiant temperature and color. Units may also require regulator
adjustment or higher manifold pressure. Follow manufacturer's Instructions carefully.
F. Contractor shall follow unit manufacturer's printed Installation and start-up instructions. Clean each unit
including venuri tube and record verification of proper operation on Gas Fired Unit Heater Start-Up
Test Report form. After each unit has been checked, started up, and adjusted, and is operating
properly, record start-up data on Gas Fired Unit Heater Start-Up Reports, located at the end of this
Section, as it Is accomplished, with date. The General Contractor shall retain the form on site and
submit to Wal- Mart's Independent Test and Balance Agency prior to start of balancing.
G. With so , a gas companies, meter - outlet pressure with full -gas demand may be lower than required to
provide recommended pressure in gas line at unit heater inlet, with resulting manifold pressure lower
than required for orifice furnished with unit heater. Where this is encountered during start-up, the
Contractor shall utilize a larger orifice to obtain correct BTUH Input per manufacturer's instructions and
so indicate on the Start-Up Report.
