WARNING

Battery electrolyte (sulfuric acid) is highly caustic

and can burn clothing and skin. Wear acid imper-

vious neoprene gloves and safety goggles, or full

face shield, when working with the batteries.

Always disconnect the negative (-) battery cable

first and attach the negative (-) battery cable last.

CAUTION

DO NOT connect battery charging cables to any

electronic control system component. This can

damage the electronic control system.

3.3.2 Battery Installation

1. Provide adequate room for servicing or replacing

the batteries. Provide protection from extremes

of temperature and weather.

2. Locate the batteries near the engine or increase

the size of the conductors as required by appli-

cable codes. Ensure that the batteries are con-

figured properly for 24 VDC standard operations.

Refer to Figure 3-1.

3. Check the battery cables and connections to

ensure they are installed correctly and in good

condition.

NOTE: Coat the terminals with NOCO/Anti-OX to

prevent corrosion. Install the cables and tighten the

battery connections.

WARNING

Batteries can emit explosive gases during charg-

ing. Always ventilate the compartment before ser-

vicing the batteries. Remove sources of spark or

open flame. To avoid arcing, remove the negative

(-) battery cable first and attach the negative (-)

battery cable last.

3.4 Exhaust System

WARNING

Inhalation of exhaust gases can result in severe

personal injury or death. Do not use exhaust heat

to warm a room, compartment or storage area.

Pipe exhaust gases to the outside of any enclosure.

Locate the exhaust outlets away from any air inlets to

avoid gases re-entering the enclosure. Exhaust

installations are subject to various detrimental condi-

tions such as extreme heat, infrequent operation and

light loads. Regularly inspect the exhaust system

both visually and audibly to see that the entire system

remains fume tight and safe for operation.

WARNING

Inhalation of exhaust gasses can result in severe

personal injury or death. Use extreme care during

installation to provide a tight exhaust system.

Terminate exhaust pipe away from enclosed or

sheltered areas, windows, doors and vents.

For indoor installation, the exhaust system shall use

sealed joint type fittings, (for example NPT fittings) to

provide a tighter exhaust system. Use of slip type fit-

tings (secured with a muffler clamp) may allow

leakage of exhaust gases into the building.

The exhaust system design should meet Federal,

State and local code requirements.

Use an approved thimble (Figure 3-2) where exhaust

pipes pass through walls or partitions. Insulated wall/

roof thimbles are used where exhaust pipes pass

through a combustible roof or wall. This includes

structures, such as wood framing or insulated steel

decking, etc. Uninsulated wall/roof thimbles are used

where exhaust pipes pass through a non-combustible

wall or roof, such as concrete. Refer to NFPA 37

Stationary Combustion Engines and Gas Turbines”

for accepted design practices. Build according to the

code requirements in effect at the installation site.
