| The Engine must be installed where a generous supply of fresh air is assured.
A portable electric light is recommended in addition to the fixed lighting of
the engine room.
The most convenient height for the crankshaft is 27 in. (68.5 cm.) above the
ground.
Keep exhaust and water pipes as short and straight as possible.
Leave a space of about 3 feet all round the engine for ease of access and
maintenance. Foundations:
Our standard foundation drawings give the dimensions of suitable concrete beds.
These dimensions are the minimum for a good solid subsoil and modification will
have to be made where the subsoil is soft, water logged, or otherwise of a
special character.
Set the engine as level as possible, packing under the engine feet with thin
metal strips, placed as close as possible to the holding down bolts.
Portable Models:
Place portable models in as level a position as possible.
Belt Drive:
Driving belts must be run as close up to the flywheel as possible to avoid undue
strain on the bearings and crankshaft. Where "fast" and "loose" pulleys are
used, drive the "fast" pulley from the side nearest the flywheel.
Through Cooling:
The cooling of an engine by passing water through it to waste, with or without
the use of a small tank, is totally unsuitable and must not be used under any
circumstances.
Exhaust Pipes:
If a longer exhaust pipe than standard must be fitted, this should at no point
slope upward from the engine, unless a suitable moisture trap is fitted at the
lowest art of the pipe. This is to prevent moisture, caused by condensation,
draining back into the cylinder and causing damage.
If more than 10 feet of pipe is used, the bore of the pipe must be increased.
Pipe sizes:
Up to 10 feet - 2 in. (50.8 mm.) bore
10 feet to 20 feet - 2½ in. (63.5 mm.) bore
over 20 feet - 3 in. (76.2 mm.) bore
To facilitate cleaning the exhaust Pipe during overhaul, it meet be erected in
easily detached sections of about 4 feet in length and not concreted in at any
Point.
