The three-dimensional real scalar model, in which the Z{sub 2} symmetry spontaneously breaks, is renormalized in a nonperturbative manner based on the Tamm-Dancoff truncation of Fock space. A critical line is calculated by diagonalizing the Hamiltonian regularized with basis functions. The marginal ({phi}{sup 6}) coupling dependence of the critical line is weak. In the broken phase the canonical Hamiltonian is tachyonic, so the field is shifted as {phi}(x){r_arrow}{var_phi}(x)+v. The shifted value v is determined as a function of running mass and coupling so that the mass of the ground state vanishes. {copyright} {ital 1997} {ital The American Physical Society}
