Chicago MONASH New York Thermostatic Return Line Traps, Adjustable and Non-Adjustable Automatic Air Valves for Radiators, Packless Radiator Supply Valves SPECIFICATIONS FOR RETURN LINE TRAPS SUBMITTED TO ARCHI TECTS AND SPECIFYING ENGINEERS TO BE EMBODIED IN THEIR SPECIFICATIONS Dear Sir:-- You are, no doubt, desirous of safe-guarding the interest of your Client, and with that point in view, we are submitting for your consideration the wording of specifications for THERMOSTATIC RETURN LINE TRAPS. Vacuum Radiator Traps "The Vacuum Radiator Trap shall be of a THERMOSTATIC TYPE, brass or iron body, nickel plated, MONASH OR ANY OTHER of approved make, and the THERMOSTATIC DIAPHRAGM in the TRAP shall be GUARANTEED against fracture or rupture on pressure up to ten pounds. \ The GUARANTEE shall be in writing for a period of TEN YEARS after date of installation and shall be delivered to the Architect in duplicate for trans mission to the Owner of the Building. The TRAPS to be installed, shall be noiseless in operation and the Manu facturer of the TRAPS shall furnish a GUARANTEE in writing that if the TRAPS do not function so, he will have them removed at his expense, and in stall in their place TRAPS that are noiseless in operation." If some such wording as above, is embodied in your specifications, it will eliminate the use of TRAPS that do not measure up to that standard, for there are TRAPS on the market, that are sold as--noiseless in operation--but in reality, have been found, wanting in this respect, hence-- You will agree with us that it is to the benefit of your Client to prote. t him against the installation of TRAPS that are NOT noiseless in operation, and against UP-KEEP COST of the DIAPHRAGM for TEN YEARS. If you desire a.copy of the TEN YEAR GUARANTEE that we furnish or any literature regarding our TRAPS, please drop us a line, and it will be forthcoming.
