GENERAL HAZARD
WARNING: Failure
to comply with the precautions and
instructions provided with this heater can
result in death, serious bodily injury, and
property loss, or damage from hazards of
fire, explosion, burn, asphyxi ation, carbon
monoxide poisoning, and/ or electrical
shock. Only persons who can understand
and follow these instructions should use or
service this heater. If you need assistance
or heater information such as an
instruction manual, labels, etc. contact the
manufacturer.
FIRE, BURN,
INHALATION AND
EXPLOSION HAZARD: Keep solid
combustibles such as building materials,
paper, or cardboard, at a safe distance
away from heater

unknown chemicals.
Not for home or
recreational vehicle
use.
This heater has been designed as a
construction heater in accordance with
ANS Z83.7 CSA 2.14. Other standards
govern the use of fuel gases and heating
products for specific uses. Your local
authority can inform you of these. The
primary purpose of these construction
heaters are to provide temporary
heating of building under construction,
alteration, or repair. When properly
used, the heater provides safe
heating. Products of combustion are vented
into the heated area.
- For either indoor or outdoor use.
Adequate ventilation must be
provided.
IMPORTANT: Every possible circumstance that might involve a hazard cannot be anticipated. The warnings in this
manual on tags or decals affixed to the
unit are not all inclusive. If a procedure,
economical
work method, or operating technique
not specifically recommended by Dayton is used, you must make sure it is
safe for you and others. You should also
ensure that equipment will not be damaged or be made unsafe by the operating or maintenance method you use.
Carbon Monoxide
poisoning may lead to
death! Some people are more affected by
Carbon Monoxide than others. Early signs
of carbon monoxide poisoning resemble
the flu, with headaches, dizziness, and/or
nausea. If you have these signs, the
heater may not be operating properly or
the area may not be sufficiently
ventilated. Get fresh air at once! Have
heater serviced.
Carefully install and
always use great care
when operating this heater. Be sure to
research and follow all local ordinances
and codes. In the absence of local codes,
with the Standard for the Storage and
Handling of Liquefied Petroleum Gases,
ANSI/NFPA 58 and the Natural Gas and
Propane Installation Code CSA B149.1.
Natural Gas: Natural gas has a very
distinctive odor that will help you
detect a leak. However, this odor
may fade in time. Natural gas may be
present in the area even though no
odor is detected.
– Use only natural gas. Do not attempt
to use propane gas. Use only factory
preset regulator provided on heater.
– Provide adequate ventilation. Before
using heater, provide at least a 3
square foot (.28 m2) opening of fresh,
outside air for every 100,000 BTU/Hr
rating.]
WARNING
This product and the fuels used to
operate this product (natural gas),
and the products of combustion
of such fuels, can expose you to
chemicals including benzene, which

Assembly
MODEL RA100NGDGD
1. Provide natural gas supply system.
2. Install plumbing to a low pressure
natural gas source to heater. The
source must be regulated to 1/2 PSI,
maximum 3/4’’ (19 mm) I.D. pipe or
flexible connector, not longer than 10
feet (3 m).
3. Be sure to use thread sealing
compound when connecting the hose
to the heater at the 1/2’’ (13 mm) NPT
fitting at the regulator inlet. Tighten
all fittings with a wrench.
4. Open natural gas supply valve
SLOWLY.
5. Check all connections for leaks.
Figure 2 – Pipe and Valve Inlet
Never use an open
flame to check for a
leak. Apply 50/50 mixture of liquid soap
and water to all joints. Bubbles forming
show a leak. Correct all leaks at once.
6. Close natural gas supply valve.
